Lars George updated HBASE-2029:
-------------------------------
Attachment: HBASE-2029-hirb-v3.patch
HBASE-2029-hirb-v3.patch adds the change to HBaseServer.java to avoid sending
the stack trace as part of the message and also adds history saving for the
last 50 commands. Otherwise it has the same content as the v2 patch.

> 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
> {noformat}
