Subject [jira] [Commented] (ACCUMULO-898) look into replacing cloudtrace
Date Thu, 09 Oct 2014 00:09:34 GMT


Billie Rinaldi commented on ACCUMULO-898:

Thanks, [~jdf]!  Jim and I collaborated on this patch.  He switched everything over to use
htrace, I worked on writing the new traces to Accumulo, and we teamed up on debugging.  This
patch would also fix ACCUMULO-1197, because tracing is automatically passed through to HDFS
with the switch to htrace.  HDFS tracing has begun to be added to Hadoop trunk, so if you
were using Accumulo on Hadoop 3.0.0-SNAPSHOT, you would see HDFS spans as shown in Jim's snapshots.

 zipkin has a reasonable visualization, and seems to work with thrift.  We should look into
replacing our tracing with one of these.
