Chandra Sekhar K updated HBASE-29194:
-------------------------------------
Description:
After the compaction complets, in replaceStoreFiles we add the compactedFiles
to the store engine, which will be picked up by the CompactedHFilesDischarger
and it will close and move those files to archieve path.
we are updating the SpaceQuota after the File Replacement by reading the size
of the compacted files. there is a low chance that CompactedHFilesDischarger
closes and archieve the file before the file size is read causing a
NullPointerException.
we can avoid this by doing the SpaceQuota updation before invoking
replaceStoreFiles on store engine.
