Subject [jira] [Created] (HBASE-8744) Enable HBase to log the entire latency profile for HDFS packets resulting in slow writes.
Date Fri, 14 Jun 2013 23:55:20 GMT
Pritam Damania created HBASE-8744:
-------------------------------------

             Summary: Enable HBase to log the entire latency profile for HDFS packets resulting
in slow writes.
                 Key: HBASE-8744
                 URL: https://issues.apache.org/jira/browse/HBASE-8744
             Project: HBase
          Issue Type: Improvement
            Reporter: Pritam Damania
            Priority: Minor


When we see WAL outliers in HBase, at times it is not clear which component in the whole stack
is slow. At facebook we are implementing per request profiling which passes profiling information
throughout the entire stack. This information can be used to determine the outliers in HBase.
