stack commented on HBASE-58:
----------------------------
Our INFO logging level is insufficient so we always want to run at DEBUG level
(but our DEBUG level is overwhelming). One approach would be to promote all
logging to be INFO level. We'd then move the obviously DEBUG back down to
DEBUG level. For instance, here's an obvious DEBUG: Everytime a filter runs
currently, it makes 4 log lines:
{code}
2008-03-13 18:16:35,972 DEBUG
org.apache.hadoop.hbase.filter.WhileMatchRowFilter: this.filterAllRemaining is
now: false
2008-03-13 18:16:35,972 DEBUG
org.apache.hadoop.hbase.filter.WhileMatchRowFilter: Filter on rowKey:null.
Result = false
2008-03-13 18:18:53,610 DEBUG
org.apache.hadoop.hbase.filter.WhileMatchRowFilter: Successfully read a
sub-filter of type: org.apache.hadoop.hbase.filter.StopRowFilter
2008-03-13 18:18:53,610 DEBUG
org.apache.hadoop.hbase.filter.WhileMatchRowFilter: Resetting.
{code}
Maybe it should make 2 or 3 at most but it should be possible to see what a
filter is up though you should have to set DEBUG to do it.
We don't have TRACE level when we go via apache-commons.
> [hbase] review and fix logging levels

> Project: Hadoop HBase
> Issue Type: Improvement
> Reporter: Jim Kellerman
> Priority: Minor
>
> Currently, the only way to tell what is really going on with an HBase cluster
> is to enable DEBUG level logging. Unfortunately, this also generates a lot of
> 'noise' messages. We need to review log messages and see which DEBUG messages
> should be promoted to INFO and if any current INFO messages should be demoted
> to debug.
> In addition, some messages are very verbose and don't really need to be. This
> should be fixed too.
> A good starting point for review would be to look at the output from
> test-contrib. Although that is not everything, it is a place to start working
> from.
