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

             Summary: Modify TableOperations online to check for table online before executing
fate operation.
                 Key: ACCUMULO-4574
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4574
             Project: Accumulo
          Issue Type: Improvement
    Affects Versions: 1.7.2
            Reporter: Ed Coleman
            Assignee: Ed Coleman
            Priority: Minor
             Fix For: 1.7.3, 1.8.1, 2.0.0


The table operations online operation executes as a fate operation. If a transaction lock
for the table is currently held (say by table compactions) the online operation will block.

This modification essentially changes the behavior of the online operation to a NOOP if the
table is currently online. If the current table state is online, then the operation returns
immediately without queuing a fate operation to set the online table to online. This eliminates
the blocking behavior of the operation if the table is already online.
