Subject [jira] [Created] (HDFS-8213) DFSClient should not instantiate SpanReceiverHost
Date Tue, 21 Apr 2015 21:03:58 GMT
Billie Rinaldi created HDFS-8213:

             Summary: DFSClient should not instantiate SpanReceiverHost
                 Key: HDFS-8213
                 URL: https://issues.apache.org/jira/browse/HDFS-8213
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Billie Rinaldi
            Priority: Critical

DFSClient initializing SpanReceivers is a problem for Accumulo, which manages SpanReceivers
through its own configuration.  This results in the same receivers being registered multiple
times and spans being delivered more than once.  The documentation says SpanReceiverHost.getInstance
should be issued once per process, so there is no expectation that DFSClient should do this.
