             Summary: Majc trace tacked onto minc trace
                 Key: ACCUMULO-3725
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3725
             Project: Accumulo
          Issue Type: Bug
          Components: trace
            Reporter: Billie Rinaldi
            Assignee: Billie Rinaldi
             Fix For: 1.7.0


[~elserj] noticed an issue where a minorCompaction trace of length 10295 ms 
also contained spans for a major compaction starting at time offset 46336 ms.  
Looking into this, it seems like MinorCompactionTask.run does the following:
{noformat}
start minc root span
try {
  minor compaction
  maybe major compaction
} finally {
  stop minc root span
}
{noformat}
The major compaction is async, so it gets initiated with the minor compaction 
span as its parent, then the minor compaction span is stopped, and at some 
point later the major compaction occurs.
