Huaxiang Sun updated HBASE-25356: --------------------------------- Affects Version/s: (was: 1.6.0) > HBaseAdmin#getRegion() needs to filter out non-regionName and > non-encodedRegionName > ----------------------------------------------------------------------------------- > > Key: HBASE-25356 > URL: https://issues.apache.org/jira/browse/HBASE-25356 > Project: HBase > Issue Type: Bug > Components: shell > Affects Versions: 2.4.0 > Reporter: Huaxiang Sun > Assignee: Huaxiang Sun > Priority: Major > > I was running shell command to major compact meta table. The implementation > is wrong because it tries to search the meta table with meta table name. This > also results in an unnecessary scan of meta table. > > majorCompactRegion() is calling HBaseAdmin#getRegion() which basically scan > meta table itself. > This command is being used by operator quite often, we need to correct it. > > This applies to split/flush command as well, which calls getRegion() with > tableName as an input. > > The solution is that getRegion() needs to filter out non-regionName and > non-encodedRegionName, this will save a query of meta table and a heavy scan > of meta table. If meta table size is large, the overhead is huge. -- This message was sent by Atlassian Jira (v8.3.4#803005)
