> 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: 2.3.3, 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.
