stack commented on HBASE-21745: ------------------------------- HBASE-22723 is about reporting holes, overlaps, etc. found during catalogjanitor scans. [~zghaobac] over in HBASE-22709 adds a chore that runs in Master that finds 'problematic regions' -- i.e. old hbck1 findings such as orphans in HDFS, regions on RS not in hbase:meta, etc. -- and then shows them on a new 'hbck report' page added to the UI (HBASE-22527 had added listing problematic regions on the head of the main master UI but HBASE-22709 moves the info to a dedicated page). After HBASE-22709 and HBASE-22723 go in, will add to the new 'hbck report' the findings from HBASE-22723 so also shows in UI. TODO: * HOWTO fix it doc added inline into 'hbck report' page * shell command to regenerate the 'hbck report' so shows fresher info. For now, fix-it is hbck2 tool. Later, we might consider moving fixing into the shell to a new hbck command. > Make HBCK2 be able to fix issues other than region assignment > ------------------------------------------------------------- > > Key: HBASE-21745 > URL: https://issues.apache.org/jira/browse/HBASE-21745 > Project: HBase > 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 > * Fix failed split and merge transactions that have failed to roll back due > to some bug (related to previous) > * -Enumerate store files to determine file level corruption and sideline > corrupt files- > * -Fix hfile link problems (dangling / broken)- -- This message was sent by Atlassian JIRA (v7.6.14#76016)
