Lars George updated HBASE-2029:
-------------------------------
Attachment: HBASE-2029-hirb.patch
Add -d and --debug support. Help:
{noformat}
LarsMacBookPro:hbase-trunk-ro larsgeorge$ bin/hbase shell -h
HBase Shell command-line options:
format Formatter for outputting results: console | html. Default:
console
format-width Width of table outputs. Default: 110 characters.
-d | --debug Set DEBUG log levels.
{noformat}
Without DEBUG switch, nice and clean:
{noformat}
LarsMacBookPro:hbase-trunk-ro larsgeorge$ bin/hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Version: 0.21.0-dev, r886052, Thu Dec 3 17:05:20 CET 2009
hbase(main):001:0> scan 'e'
NativeException: org.apache.hadoop.hbase.TableNotFoundException: e
hbase(main):002:0> exit
{noformat}
And with DEBUG switch, verbose as requested:
{noformat}
LarsMacBookPro:hbase-trunk-ro larsgeorge$ bin/hbase shell -d
Setting DEBUG log level...

One last thing I could think of is to set the @CONF[:BACK_TRACE_LIMIT] = 0
according to that switch as well. So that with DEBUG enabled it also logs the
full details from the ruby scripts.
> Reduce shell exception dump on console

> Key: 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-hirb.patch, 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.
> {noformat}
> ...
> [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
