---------------------------------------------------------

I plan to dig some more into distcp code - likely the copy succeeded on subsequent attempt.

But what confuses me was that the two WAL files in 'FSHLog$SyncRunner(1275): syncing writer'
logs in the earlier snippet didn't encounter the  Mismatch in length error.
Meaning, even without the 'Mismatch in length', likely the test would still fail.
