Huaxiang Sun updated HBASE-25356:
---------------------------------
Description:
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 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.
