Hi Stephen,
Thank you for your reply. It was very helpful.
This weekend everything was working fine, but when I came back to the office,
the performance was slow again.
I checked the jobtracker and tasktracker and narrowed it down to; Shuffle
Error: Exceeded MAX_FAILED_UNIQUE_FETCHES; bailing-
I am trying to upgrade from Hive 0.10 to 0.12, but I am stuck trying to
debug an error I keep getting. I have a couple of SerDes that I have
developed, but when I try to query tables with these SerDes I get a
ClassNotFoundException for the SerDe class. I know that the jar files have
been loaded OK,
