Phabricator commented on HBASE-4542:
------------------------------------
mbautin has commented on the revision "[jira] [HBASE-4542] Add filter info to
slow query logging".
@zhiqiu: don't worry about filling those fields in the "Submit Patch" form.
We can correct those fields later if necessary. The purpose of setting JIRA
status to "Patch Available" is to make the Apache Jenkins continuous
integration server pick up the patch and run a subset of the test suite
("small" and "Medium" tests) against it.
In some cases, the format of the patch automatically generated by Phabricator
and uploaded to JIRA is such that it cannot be applied by the standard patch
command for some reason. In those cases, Hadoop QA (Jenkins server) will post
an update to the JIRA saying that it could not apply the patch. If that
happens, you can generate a patch manually using the following command:
git format-patch --no-prefix HEAD^..HEAD
Then, upload this patch to the JIRA
(https://issues.apache.org/jira/browse/HBASE-4542) using the "+" button at the
top of the "Attachments" section of the page.

> Slow query log doesn't report filters in effect.
> For example:
> {code}
> (operationTooSlow): \
> {"processingtimems":3468,"client":"10.138.43.206:40035","timeRange":
> [0,9223372036854775807],\
> "starttimems":1317772005821,"responsesize":42411, \
> "class":"HRegionServer","table":"myTable","families":{"CF1":"ALL"]},\
> "row":"6c3b8efa132f0219b7621ed1e5c8c70b","queuetimems":0,\
> "method":"get","totalColumns":1,"maxVersions":1,"storeLimit":-1}
> {code}
> the above would suggest that all columns of myTable:CF1 are being requested
> for the given row. But in reality there could be filters in effect (such as
> ColumnPrefixFilter, ColumnRangeFilter, TimestampsFilter() etc.). We should
> enhance the slow query log to capture & report this information.
