stack commented on HBASE-2029:
------------------------------
According to http://ruby-doc.org/docs/ProgrammingRuby/html/irb.html, should be
able to do something like this in our subclass of Irb:
{code}
Index: bin/hirb.rb

IRB.setup(ap_path)

I'll play w/ it and get back to you.
> Reduce shell exception dump on console
> --------------------------------------

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

> Attachments: HBASE-2029.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}
