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

             Summary: DirectoryDecommissioner#getBackupName() shouldn't compute absolute value
of signed random integer
                 Key: ACCUMULO-2284
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2284
             Project: Accumulo
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


{code}
    return new Path(path.getParent(), path.getName() + "_" + System.currentTimeMillis() +
"_" + Math.abs(rand.nextInt()) + ".bak");
{code}
this is because Math.abs can actually return negative result for integer input:
{code}
assertTrue( Math.abs(Integer.MIN_VALUE) < 0 );
{code}
