Subject [jira] Created: (HBASE-2029) Reduce shell exception dump on console
Date Thu, 03 Dec 2009 22:42:20 GMT
Reduce shell exception dump on console

                 Key: HBASE-2029
                 URL: https://issues.apache.org/jira/browse/HBASE-2029
             Project: Hadoop HBase
          Issue Type: Improvement
    Affects Versions: 0.20.2
            Reporter: Lars George
            Priority: Minor
             Fix For: 0.21.0

As discussed on IRC and seen over and over, the shell is too verbose when it prints Java related
exceptions. The huge stack trace on the console is often causing more harm then actually helping.

[11:31pm] larsgeorge:
the only concern is to keep it in sync with new changes and also reduce its stacktrace
[11:31pm] larsgeorge:
that can be quite nasty
[11:31pm] _dodger_:
I've seen a prime example of that on the mailing list today
[11:32pm] larsgeorge:
yeah, those do repeat themselves
[11:32pm] larsgeorge:
also that DEBUG is on by default
[11:33pm] larsgeorge:
mind you, that is a good idea for the daemons
[11:33pm] larsgeorge:
but prolly not the shell
[11:33pm] jdcryans:
I was thinking
[11:33pm] larsgeorge:
maybe we can set ERROR logging level just for the shell when it is started?
[11:34pm] jdcryans:
we should stop printing the stack trace for NSRE
[11:34pm] larsgeorge:
there are a few others of that sort
[11:34pm] larsgeorge:
be it ZK reconnects etc.
[11:35pm] jdcryans:
yeah there's a lot of hbase-generated zk-related noise
