All but one of them were also squashed into the first commit of the current PR when carried over from the prior PR. I think instead of referencing them in the commit I'm going to re-resolve them as "feedback received" and leave the fix version blank. that should make it easy to tell the difference between those and the subtasks that need to happen as followup, since those will get a normal resolution and a fix version. > Distributed MOB compactions > > > Key: HBASE-22749 > URL: https://issues.apache.org/jira/browse/HBASE-22749 > Project: HBase > Issue Type: New Feature > Components: mob >Reporter: Vladimir Rodionov >Assignee: Vladimir Rodionov >Priority: Major > Attachments: HBASE-22749-branch-2.2-v4.patch, > HBASE-22749-master-v1.patch, HBASE-22749-master-v2.patch, > HBASE-22749-master-v3.patch, HBASE-22749-master-v4.patch, > HBASE-22749_nightly_Unit_Test_Results.csv, > HBASE-22749_nightly_unit_test_analyzer.pdf, HBase-MOB-2.0-v3.0.pdf > > > There are several drawbacks in the original MOB 1.0 (Moderate Object > Storage) implementation, which can limit the adoption of the MOB feature: > # MOB compactions are executed in a Master as a chore, which limits > scalability because all I/O goes through a single HBase Master server. > # Yarn/Mapreduce framework is required to run MOB compactions in a scalable > way, but this won’t work in a stand-alone HBase cluster. > # Two separate compactors for MOB and for regular store files and their > interactions can result in a data loss (see HBASE-22075) > The design goals for MOB 2.0 were to provide 100% MOB 1.0 - compatible > implementation, which is free of the above drawbacks and can be used as a > drop in replacement in existing MOB deployments.

I'm attaching a PDF of the summary of the results and a CSV with individual test pass/fail status. Essentially it looks equivalent to master. the new tests look stable, and it's a random smattering of things that fail out with execution environment problems. (in the the last build the 1 test that failed was due to a local FS permission issue) I'll rebase to current master again and aim to get the commit history at one-commit-per-jira. I think some of the subtasks are already squashed in the current history, so I'll aim to get their JIRA keys in the commit message so we at least can grep for them. Since this obviates the dataloss in HBASE-22075, after merge to master I'm going to chase down the remaining subtasks so that I can then get this into branches-2. > Distributed MOB compactions > > > Key: HBASE-22749 > URL: https://issues.apache.org/jira/browse/HBASE-22749 > Project: HBase > Issue Type: New Feature > Components: mob >Reporter: Vladimir Rodionov >Assignee: Vladimir Rodionov >Priority: Major > Attachments: HBASE-22749-branch-2.2-v4.patch, > HBASE-22749-master-v1.patch, HBASE-22749-master-v2.patch, > HBASE-22749-master-v3.patch, HBASE-22749-master-v4.patch, > HBase-MOB-2.0-v3.0.pdf > > > There are several drawbacks in the original MOB 1.0 (Moderate Object > Storage) implementation, which can limit the adoption of the MOB feature: > # MOB compactions are executed in a Master as a chore, which limits > scalability because all I/O goes through a single HBase Master server. > # Yarn/Mapreduce framework is required to run MOB compactions in a scalable > way, but this won’t work in a stand-alone HBase cluster. > # Two separate compactors for MOB and for regular store files and their > interactions can result in a data loss (see HBASE-22075) > The design goals for MOB 2.0 were to provide 100% MOB 1.0 - compatible > implementation, which is free of the above drawbacks and can be used as a > drop in replacement in existing MOB deployments.

> There are several drawbacks in the original MOB 1.0 (Moderate Object
> Storage) implementation, which can limit the adoption of the MOB feature:
> # MOB compactions are executed in a Master as a chore, which limits
> scalability because all I/O goes through a single HBase Master server.
> # Yarn/Mapreduce framework is required to run MOB compactions in a scalable
> way, but this won’t work in a stand-alone HBase cluster.
> # Two separate compactors for MOB and for regular store files and their
> interactions can result in a data loss (see HBASE-22075)
> The design goals for MOB 2.0 were to provide 100% MOB 1.0 - compatible
> implementation, which is free of the above drawbacks and can be used as a
> drop in replacement in existing MOB deployments. So, these are design goals
> of a MOB 2.0:
> # Make MOB compactions scalable without relying on Yarn/Mapreduce framework
> # Provide unified compactor for both MOB and regular store files
> # Make it more robust especially w.r.t. to data losses.
> # Simplify and reduce the overall MOB code.
> # Provide 100% compatible implementation with MOB 1.0.
> # No migration of data should be required between MOB 1.0 and MOB 2.0 - just
> software upgrade.

> Project: HBase
> Issue Type: New Feature
> Components: mob
>Reporter: Vladimir Rodionov
>Assignee: Vladimir Rodionov
>Priority: Major
> Attachments: HBASE-22749-branch-2.2-v4.patch,
> HBASE-22749-master-v1.patch, HBASE-22749-master-v2.patch,
> HBase-MOB-2.0-v1.pdf, HBase-MOB-2.0-v2.1.pdf, HBase-MOB-2.0-v2.2.pdf,

>
> There are several drawbacks in the original MOB 1.0 (Moderate Object
> Storage) implementation, which can limit the adoption of the MOB feature:
> # MOB compactions are executed in a Master as a chore, which limits
> scalability because all I/O goes through a single HBase Master server.
> # Yarn/Mapreduce framework is required to run MOB compactions in a scalable
> way, but this won’t work in a stand-alone HBase cluster.
> # Two separate compactors for MOB and for regular store files and their
> interactions can result in a data loss (see HBASE-22075)
> The design goals for MOB 2.0 were to provide 100% MOB 1.0 - compatible
> implementation, which is free of the above drawbacks and can be used as a
> drop in replacement in existing MOB deployments. So, these are design goals
> of a MOB 2.0:
> # Make MOB compactions scalable without relying on Yarn/Mapreduce framework
> # Provide unified compactor for both MOB and regular store files
> # Make it more robust especially w.r.t. to data losses.
> # Simplify and reduce the overall MOB code.
> # Provide 100% compatible implementation with MOB 1.0.
> # No migration of data should be required between MOB 1.0 and MOB 2.0 - just
> software upgrade.

I just got a clean build off of branch-2.2 ref {{ }}.
Since branch-2.2 is going through release candidates ATM, the version numbers
don't have SNAPSHOT in them, so you have to be careful to keep Maven from using
an artifact from an old build. I use the following line, but you have to be
careful because it will forcibly delete any untracked changes in the local
working directory:
{code}
git clean -xdf && rm -rf ~/.m2/repository/org/apache/hbase/* && mvn
-Dtest=NoTests -Dit.test=NOITs package install verify

bq. Need to expressly state wether or not this change to per-region accounting
plans to alter the current assumptions that use of the feature means that the
MOB data isn’t counted when determining region size for decisions to normalize
or split.
This part has not been touched - meaning that MOB 2.0 does exactly the same
what MOB 1.0 does. If MOB is not counted for normalize/split decision now in
MOB it won'y be in 2.0. Should it? Probably, yes. But it is not part of
scalable compactions.
{quote}
not counted is exactly what I'd prefer to hear. :) if/when anyone wants to add
that I'd strongly recommend making sure we can independently tune the threshold
for mob vs non-mob for those decisions.

Good question. Default (non partial) major compaction does have the same or
similar to regular HBase tiered compaction WA. I would not call this unbounded,
but it is probably worse than in MOB 1.0. Partial MOB compaction will
definetely have a bounded WA comparable to what we have in MOB 1.0 (where
compaction is done by partitions and partitions are date-based)
The idea of partial major MOB compaction is either to keep total number of MOB
files in a system under control (say - around 1 M), or do not compact MOB files
which reached some size threshold (say 1GB). The latter case is easier to
explain. If you exclude all MOB files above 1GB from compaction - your WA will
be bounded by log2(T/S), where log2 - logarithm base 2, T - maximum MOB file
size (threshold) and S - average size of Memstore flush. This is approximation
of course. How it compares to MOB 1.0 partitioned compaction? By varying T we
can get any WA we want. Say, if we set limit on number of MOB files to 10M we
can decrease T to 100MB and it will give us total capacity for MOB data to 1PB.
With 100MB threshold, WA can be very low (low one's). I will update the
document and will add more info on partial major MOB compactions, including
file selection policy.

> drop in replacement in existing MOB deployments. So, these are design goals
> of a MOB 2.0:
> # Make MOB compactions scalable without relying on Yarn/Mapreduce framework
> # Provide unified compactor for both MOB and regular store files
> # Make it more robust especially w.r.t. to data losses.
> # Simplify and reduce the overall MOB code.
> # Provide 100% compatible implementation with MOB 1.0.
> # No migration of data should be required between MOB 1.0 and MOB 2.0 - just
> software upgrade.

[jira] [Commented] (HBASE-22749) Distributed MOB compactions
[ https://issues.apache.org/jira/browse/HBASE-22749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16909365#comment-16909365 ] Sean Busbey commented on HBASE-22749: - h2. region sizing - splitting, normalizers, etc Need to expressly state wether or not this change to per-region accounting plans to alter the current assumptions that use of the feature means that the MOB data isn’t counted when determining region size for decisions to normalize or split. h2. write amplification Current description of the unified compactor’s handling of MOB data doesn’t include anything about doing the kind of mob file partitioning that was previously done. I think this will behave a lot like the example from Section 3.1.1 in the MOB Design v5 document you reference, specifically where MOB stuff is segregated in a dedicated CF. We still end up getting unbounded write amplification. Consider this use case, which I think is in line with the assumptions laid out in both your description and in the MOB Design v5 document: * Table with 50k regions * MOB values that are 300KiB * No updates, no deletes * periodic flushes set to 6 hours * periodic major and mob compaction set to weekly * infrequent writes (slow enough so that only periodic flushes happen, but enough that all regions have a mob write) Under the current MOB implementation with a monthly partition policy, I can reason that: * we’ll be generating 200k hfiles in the mob directory per day due to periodic flushes * at the first week we’ll have 1.4m new hfiles, which we’ll compact probably into a low-double-digit number of hfiles * at the second week, we’ll have 1.4m new hfiles plus the results of the first compaction. we will probably compact this into a low-double-digit number of hfiles * at the third week, same thing again * on the fourth week, same thing again * After that fourth week things repeat, but the files generated will be in a new partition and so anything from prior won’t be rewritten again. In the steady state: * we should have a number of hfiles that stays under the limits of HDFS * for a given MOB value, we should only write it to HDFS no more than 5 times (flush + between 1 and 4 compactions) So that means we have a write amplification of ~5x regardless of splits or merges from normalization. For the new design I don’t think there’s currently any bound. If I use the default compaction strategy: * We’ll still be generating 200k hfiles per day * at the first week we’ll have 1.4m new hfiles which we’ll compact to 50k hfiles. * at the end of second week we’ll have 1.4m new hfiles + the existing 50k hfiles, and we’ll compact to 50k hfiles * third week, same thing * forth week, same thing * this will repeat until each of the 50k files hits 10 GiB - 20 GiB depending on configs (~35-70k cells) At the extreme of exactly 1 mob value per region per periodic flush that would mean 1-2 thousand weeks. Splits over that time period would mean probably we’d keep rewriting indefinitely. So the amount of amplification is essentially going to be driven by the periodicity of the mob compaction chore. With default configs we can still get memstores that have ~1GiB of MOB values and still only do periodic flushes, so this can remain a non-trivial amount of load on HDFS. If we enable partial major mob compaction we’d avoid writing the values repeatedly, but we’d against HDFS limitations in ~10 days. h2. MOB compaction request chore and Partial major mob compaction It’s a bit confusing going through the “Partial major MOB compaction” section where it currently is in the write up. As I understand things, you’re essentially describing a strategy for the process that has to pick particular regions to issue major compaction requests against instead of just requesting the whole table be compacted. Since this is an optimization of cluster IO use that’s possible _once we have per-region accounting and maintenance of MOB data_ I think it’d be clearer if it was in a section _after_ you describe the “scalable MOB compactions” stuff. instead of starting that section off with the description of the compaction request chore, you can explain the accounting changes to store maintenance, the resulting changes to cleaning, and then end with the explanation about how folks won’t have to schedule maintenance tasks themselves with a section that’s labeled as the description of the “MOB Compaction Request Chore” and include there the description fo the region prioritization strategy. Another good strategy to mention there is prioritizing the store files we know haven’t been converted to include accounting information the cleaner needs. h2. split tracking for the above Could we do this with entries in hbase:meta or a journal instead of individual files? It’s going to get very messy when there are tables with tens-of-thousands or hundreds-of-thousands of regions. h2.
