stack commented on HBASE-20507: ------------------------------- So, IIUC, this is different to what I see over in HBASE-20503 where I am writing a WAL and then it breaks ("Stream already broken"). In this case we roll the WAL and try to recover the file we had been writing too -- the one that was reporting "stream already broken" -- in the stream's recoverAndClose. Do we need to recover the lease in recoverAndClose? On this patch, LGTM. Nice test. On the javac warning, I don't know how to avoid. Perhaps someone else does. Meantime push it I'd say. > Do not need to call recoverLease on the broken file when we fail to create a > wal writer > --------------------------------------------------------------------------------------- > > Key: HBASE-20507 > URL: https://issues.apache.org/jira/browse/HBASE-20507 > Project: HBase > Issue Type: Improvement > Components: wal > Reporter: Duo Zhang > Assignee: Duo Zhang > Priority: Major > Fix For: 2.0.1 > > Attachments: HBASE-20507.patch > > > I tried locally with a UT, if we overwrite a file which is currently being > written, the old file will be completed and then deleted.
