[jira] Commented: (MAPREDUCE-1185) URL to JT webconsole for running job and job history should be the same

I think the approach of including the job history file name in the URL since the beginning will cause more headaches, since the job history file name includes some things that are unparseable by humans. This will require a map between job ids and the file name to be kept inside the jobtracker, Since URL is given by the JobClient API, the thinking was that users don't really need to bother about the contents and map based thing will not survive JT restarts. The long term solution being done by MAPREDUCE-323. Saying that it looks like (also based on off line discussion with Arun) that map based solution is acceptable in medium term until MAPREDUCE-323 is done. bq. but that should not be too big, since the entries can be removed when job history is purged periodically. Makes sense ? Yes, that should work. The only problem we also need to keep in mind that when history cleaner thread runs, it does a listing of the files in history folder and deletes the ones which are older than 30 days (default). But in the meanwhile operations could have manually purged the files. So those entries won't be purged from the map. To address this timestamp can be maintained along with the history file name. > URL to JT webconsole for running job and job history should be the same > --- > > Key: MAPREDUCE-1185 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1185 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: jobtracker >Reporter: Sharad Agarwal >Assignee: Sharad Agarwal > Attachments: 1185_v1.patch, 1185_v2.patch, 1185_v3.patch, > 1185_v4.patch > > > The tracking url for running jobs and the jobs which are retired is > different.

[jira] Updated: (MAPREDUCE-1222) [Mumak] We should not include nodes with numeric ips in cluster topology.
[ https://issues.apache.org/jira/browse/MAPREDUCE-1222?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Dick King updated MAPREDUCE-1222: - Attachment: IPv6-predicate.patch This is a supplement to the previous patch to expand the regexp to meet the requirements of RFC 4291 . The regular expression and the finite state machine that supports it is longer than it needs to be -- about 2.6K, and probably about 500-1000 nodes in the FSM. I did it this way to avoid as much backtracking as possible. It seems to take about 10 microseconds to handle an IPV6 full address, a bit more for an address with elisions, a bit less for an IPV4 address, and about 5 microseconds for a non-numeric address. I'll open the regular expression for comment before I fold it in with the patch and with other changes I've suggested in the main patch. > [Mumak] We should not include nodes with numeric ips in cluster topology. > - > > Key: MAPREDUCE-1222 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1222 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: contrib/mumak >Affects Versions: 0.21.0, 0.22.0 >Reporter: Hong Tang >Assignee: Hong Tang > Fix For: 0.21.0, 0.22.0 > > Attachments: IPv6-predicate.patch, mapreduce-1222-20091119.patch, > mapreduce-1222-20091121.patch > > > Rumen infers cluster topology by parsing input split locations from job > history logs.

Also, the documentation should say what happens if the maxTasks of a pool is set lower than its minTasks: in this case, the maxTasks takes precedence. It might also be good to print a warning in PoolManager when loading a config file if we see a pool with maxTasks < minTasks. You should do this after you finish reading the a element. One other very minor thing - there seem to be some tabs in the patch, replace them with spaces.

You might want to just svn revert it. * What is the purpose of the changes to build-contrib.xml? Are they just something you copied in from another build.xml file? * In the unit test, it would be good to submit the jobs first (with an advanceTime between them) before doing any checkAssignment's, so that both jobs are initially available. Note that the scheduler will probably alternate between assigning tasks from the two jobs in this case, but it should still not let job 1 go over its max share. * In the web UI, can you call the new "Max" column "Max Share" instead, so it is more consistent with the other column names? * You can simplify Pool.numRunningTasks(TaskType type) to just return getSchedulable(type).getRunningTasks(). It might also be good to rename the method to getRunningTasks instead of nunRunningTasks so that it's more consistent with the rest of the code. * Instead of making PoolSchedulable.getDemand() return maxTasks if demand > maxTasks, it would be better to change PoolSchedulable.updateDemand() to cap the demand at the end of the method, so that getDemand() just returns demand. Otherwise, it will be a little confusing to have a variable called demand in PoolSchedulable whose value is not the same as that returned by getDemand(). > Per-pool task limits for the fair scheduler > --- > > Key: MAPREDUCE-698 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-698 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: contrib/fair-share >Reporter: Matei Zaharia > Fix For: 0.21.0 > > Attachments: MAPREDUCE-698-prelim.patch, mapreduce-698-trunk.patch, > mapreduce-698-trunk.patch > > > The fair scheduler could use a way to cap the share of a given pool similar > to MAPREDUCE-532. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
[jira] Commented: (MAPREDUCE-1229) [Mumak] Allow customization of job submission policy

]
Dick King commented on MAPREDUCE-1229:
--
1: Should {{TestSimulator*JobSubmission}} check to see whether the total
"runtime" was reasonable for the Policy?
2: minor nit: Should {{SimulatorJobSubmissionPolicy/getPolicy(Configuration)}}
use {{valueOf(policy.toUpper())}} instead of looping through the types?
3: medium sized nit: in {{SimulatorJobClient.isOverloaded()}} there are two
literals, 0.9 and 2.0F, that ought to be {{static private}} named values.
4: Here is my biggest point. The existing code cannot submit a job more often
than once every five seconds when the jobs were spaced further apart than that
and the policy is {{STRESS}} .
Please consider adding code to call the {{processLoadProbingEvent}} core code
when we {{processJobCompleteEvent}} or a {{processJobSubmitEvent}} . That
includes potentially adding a new {{LoadProbingEvent}} . This can lead to an
accumulation because each {{LoadProbingEvent}} replaces itself, so we should
track the ones that are in flight in a {{PriorityQueue}} and only add a new
{{LoadProbingEvent}} whenever the new event has a time stamp strictly earlier
than the earliest one already in flight. This will limit us to two events in
flight with the current {{adjustLoadProbingInterval}} .
If you don't do that, then if a real dreadnaught of a job gets dropped into the
system and the probing interval gets long it could take us a while to notice
that we're okay to submit jobs, in the case where the job has many tasks
finishing at about the same time, and we could submit tiny jobs as onsies every
five seconds when the cluster is clear enough to accommodate lots of jobs.
When the cluster can handle N jobs in less than 5N seconds for some N, we won't
overload it with the existing code.

Dick King commented on MAPREDUCE-1222:
--
1: Should we worry about IPV6 numeric addresses? I'll write the regex if you
want.
2: Proposed line 249 of {{SimulatorEngine.java}} reads:
{{// ips and as host names. We remove them from the parsed network topology}}
and should read
{{// ips [as opposed to host names]. We remove numeric ips from the parsed
network topology}}
The former wording implies that we remove _both forms_ of a doubled address.
3: Do we mean to make {{isIPAddress}} part of the package local API?
3a: If not, testing {{isIPAddress}} should be accomplished by making the
addresses that superficially look like IPs but aren't part of the test case in
{{topo-with-numeric-ips.json}} .

[ https://issues.apache.org/jira/browse/MAPREDUCE-1231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12781830#action_12781830 ] Venkatesh S commented on MAPREDUCE-1231: Arun, this feature was added in H20 and was not available in H18.
