stack updated HBASE-21745:
--------------------------
Hadoop Flags: Reviewed
Release Note:
This issue adds via its subtasks:
* An 'HBCK Report' page to the Master UI added by
HBASE-22527+HBASE-22709+HBASE-22723+ (since 2.1.6, 2.2.1, 2.3.0). Lists
consistency or anomalies found via new hbase:meta consistency checking
extensions added to CatalogJanitor (holes, overlaps, bad servers) and by a new
'HBCK chore' that runs at a lesser periodicity that will note filesystem
orphans and overlaps as well as the following conditions:
** Master thought this region opened, but no regionserver reported it.
** Master thought this region opened on Server1, but regionserver reported
Server2
** More than one regionservers reported opened this region
Both chores can be triggered from the shell to regenerate ‘new’ reports.
* Means of scheduling a ServerCrashProcedure (HBASE-21393).
* An ‘offline’ hbase:meta rebuild (HBASE-22680).
* Offline replace of hbase.version and hbase.id
* Documentation on how to use completebulkload tool to ‘adopt’ orphaned data
found by new HBCK2 ‘filesystem’ check (see below) and ‘HBCK chore’ (HBASE-22859)
* A ‘holes’ and ‘overlaps’ fix that runs in the master that uses new
bulk-merge facility to collapse many overlaps in the one go.
* hbase-operator-tools HBCK2 client tool got a bunch of additions:
** A specialized 'fix' for the case where operators ran old hbck 'offlinemeta'
repair and destroyed their hbase:meta; it ties together holes in meta with
orphaned data in the fs (HBASE-22567)
** A ‘filesystem’ command that reports on orphan data as well as bad
references and hlinks with a ‘fix’ for the latter two options (based on hbck1
facility updated).
** Adds back the ‘replication’ fix facility from hbck1 (HBASE-22717)
> Make HBCK2 be able to fix issues other than region assignment

> Issue Type: Umbrella
> Components: hbase-operator-tools, hbck2
> Reporter: Duo Zhang
> Assignee: stack
> Priority: Critical
>
> This is what [~apurtell] posted on mailing-list, HBCK2 should support
> * -Rebuild meta from region metadata in the filesystem, aka offline meta
> rebuild.-
> * -Fix assignment errors (undeployed regions, double assignments (yes,
> should not be possible), etc)- (See
> https://issues.apache.org/jira/browse/HBASE-21745?focusedCommentId=16888302&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16888302)
> * -Fix region holes, overlaps, and other errors in the region chain- (See
> HBASE-22796 and HBASE-22771 -- adds hole and overlap fixing to master; hbck2
> client can as for a fixMeta).
> * -Fix failed split and merge transactions that have failed to roll back due
> to some bug (related to previous)- (Previous items 'overlaps' will take care
> of these).
> * -Enumerate store files to determine file level corruption and sideline
> corrupt files-
> * -Fix hfile link problems (dangling / broken)-
