High frequency of adaptor registration and unregistration could prevent existing adaptor to
stall
-------------------------------------------------------------------------------------------------

                 Key: CHUKWA-426
                 URL: https://issues.apache.org/jira/browse/CHUKWA-426
             Project: Hadoop Chukwa
          Issue Type: Bug
          Components: data collection
         Environment: Redhat EL 5.1, Java 6
            Reporter: Eric Yang
            Priority: Minor


The existing adaptor might not retrieve data because agent was designed to loop through the
adaptors to send the information.  When the frequency of registering and unregistering is
more frequent than chunk writer, like many tasks attempting to stream their metrics over,
the existing adaptors do not get loops.  The easy workaround is to have socket appender ready,
and we don't need to worry about this issue.  However, this is still an general issue, if
the chunk writer write time is longer than registration interval with high registration frequencies.
