----------------------------------------

             Summary: Improve how AsyncSpanReceiver drops short spans
                 Key: ACCUMULO-3863
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3863
             Project: Accumulo
          Issue Type: Bug
          Components: trace
    Affects Versions: 1.7.0, 1.6.2, 1.6.1, 1.6.0, 1.5.2, 1.5.1, 1.5.0
            Reporter: Billie Rinaldi
            Assignee: Billie Rinaldi
             Fix For: 1.6.3, 1.7.1


It just occurred to me that we are dropping 0ms spans when we poll the sendQueue for a span
to deliver via thrift.  It would cause less churn in the queue if we dropped the span as soon
as we received it, before inserting it into the queue.

This is already fixed in 1.6.3 which no longer drops 0ms spans.  It is only really a concern
in 1.7.0 if you are using HDFS tracing, which generates a LOT of 0ms spans.
