Duo Zhang updated HBASE-20839:
------------------------------
Resolution: Fixed
Hadoop Flags: Reviewed
Release Note:
As we hack into the internal of DFSClient when implementing AsyncFSWAL to get
better performance, a patch release of hadoop can make it broken.
So now, if user does not specify a wal provider, then we will first try to use
'asyncfs', i.e, the AsyncFSWALProvider. If we fail due to some compatible
issues, we will fallback to 'filesystem', i.e, FSHLog.
Status: Resolved (was: Patch Available)
Pushed to branch-2.0+. Thanks [~openinx] for reviewing.
> Fallback to FSHLog if we can not instantiated AsyncFSWAL when user does not
> specify AsyncFSWAL explicitly
