[jira] [Created] (HBASE-18398) Snapshot operation fails with FileNotFoundException

Ashu Pachauri created HBASE-18398:
-------------------------------------

             Summary: Snapshot operation fails with FileNotFoundException
                 Key: HBASE-18398
                 URL: https://issues.apache.org/jira/browse/HBASE-18398
             Project: HBase
          Issue Type: Sub-task
          Components: snapshots
            Reporter: Ashu Pachauri


Failing to take snapshot due to FileNotFoundException
    * FlushSnapshotSubprocedure.RegionSnapshotTask takes a region level read lock
    * Call to HRegion#addRegionToSnapshot.
    * Call to SnapshotManifest#addRegion. This gets the current list of store files.
    * RACE → File is marked as compacted away and HFileArchiver moves the file to archive under store level lock.
    * SnapshotManifest#addRegion visits the stale list of store files one by one. It does a file.getStatus() call to get length of each file. Since the file object still points to the original file, file.getStatus() fails with FileNotFoundException.
