Keith Turner commented on ACCUMULO-2050:
----------------------------------------
I looked into this. HadoopLogCloser currently calls recoverLease() on
DistributedFileSystem. In the case of this exception instead of a
DistributedFileSystem we have a ViewFileSystem (there error message is
misleading ACCUMULO-2063) AFAICT ViewFileSystem does not provide a way to
translate a viewfs:// path to a hdfs:// path in its API. This would be needed
to get the corresponding DistributedFileSystem. So it seems like the options
are to not support viewfs or to re-implement the viewfs translation logic in
Accumulo. I opened HDFS-5684 in the course of investigating this. I would
really like to support viewfs, so I am going to keep poking at this. If
anyone has suggestions I would love to hear them.
