| <div class="block">Distributes the task of log splitting to the available region servers. |
| Coordination happens via coordination engine. For every log file that has to be split a |
| task is created. SplitLogWorkers race to grab a task. |
| |
| <p>SplitLogManager monitors the tasks that it creates using the |
| timeoutMonitor thread. If a task's progress is slow then |
| <a href="../../../../../org/apache/hadoop/hbase/coordination/SplitLogManagerCoordination.html#checkTasks--"><code>SplitLogManagerCoordination.checkTasks()</code></a> will take away the |
| task from the owner <a href="../../../../../org/apache/hadoop/hbase/regionserver/SplitLogWorker.html" title="class in org.apache.hadoop.hbase.regionserver"><code>SplitLogWorker</code></a> |
| and the task will be up for grabs again. When the task is done then it is |
| deleted by SplitLogManager. |
| |
| <p>Clients call <a href="../../../../../org/apache/hadoop/hbase/master/SplitLogManager.html#splitLogDistributed-org.apache.hadoop.fs.Path-"><code>splitLogDistributed(Path)</code></a> to split a region server's |
| log files. The caller thread waits in this method until all the log files |
| have been split. |
| |
| <p>All the coordination calls made by this class are asynchronous. This is mainly |
| to help reduce response time seen by the callers. |
| |
| <p>There is race in this design between the SplitLogManager and the |
| SplitLogWorker. SplitLogManager might re-queue a task that has in reality |
| already been completed by a SplitLogWorker. We rely on the idempotency of |
| the log splitting task for correctness. |
| |
| <p>It is also assumed that every log splitting task is unique and once |
| completed (either with success or with error) it will be not be submitted |
| again. If a task is resubmitted then there is a risk that old "delete task" |
| can delete the re-submission.</div> |

| threads waiting on a completion. For example, if the zk-based implementation, we will scan the |
| '/hbase/splitWAL' dir every time through this loop. If there are lots of WALs to |
| split -- could be tens of thousands if big cluster -- then it will take a while. If |
| the Master has many SCPs waiting on wal splitting -- could be up to 10 x the configured |
| PE thread count (default would be 160) -- then the Master will be putting up a bunch of |
| load on zk.</div> |
