stack updated HBASE-8629:
-------------------------
Description:
At the moment I am trying to debug failures on a laptop. As is, all I can see
(w/ a small font) most of the time is timestamp, thread name, and class name
and then I have to scroll right. This is untenable, frustrating debug. Our
logs need to be less profuse and more dense.
+ Our thread names are nice and descriptive and are useful particularly when
running standlone mode but it gets silly printing out full thread names when
distributed on each log (we could turn off printing thread name but can be
helpful).
+ Do we have to print the fully qualified path for all files every time? Lines
get really long and hard to read. Ditto for region names.
+ Can we print out just the class name rather than full package qualified class
name.
For example:
{code}
2013-05-25 12:21:01,912 DEBUG
[RS_OPEN_REGION-sss-2.ent.cloudera.com,60020,1369507494038-2]
org.apache.hadoop.hbase.regionserver.handler.OpenRegionHandler: region
transitioned to opened in zookeeper: {NAME =>
'IntegrationTestDataIngestWithChaosMonkey,c28f5c19,1369509660096.4e91d414f14a75cf367609ce9c4377c7.',
STARTKEY => 'c28f5c19', ENDKEY => 'ccccccbc', ENCODED =>

sss-2.ent.cloudera.com,60020,1369507494038
{code}
Should the above just be:
{code}
2013-05-25 12:21:01,912 DEBUG

{code}
+ Some logging is bound to freak operators. We print out the full stack trace
when we are logging failed assignment because of connection refused.
+ Should make sure we tell a decent story when INFO level only enabled. At
moment it is scattershot.
