org.apache.hadoop.hbase.coordination.SplitLogManagerCoordination

Coordination for SplitLogManager. It creates and works with tasks for split log operations
Manager prepares task by calling {@link #prepareTask} and submit it by{@link #submitTask(String)}. After that it periodically check the number of remaining tasks by {@link #remainingTasksInCoordination()} and waits until it become zero.

Methods required for task life circle:
{@link #markRegionsRecovering(ServerName,Set)} mark regions for log replaying. Used by{@link MasterFileSystem}
{@link #removeRecoveringRegions(Set,Boolean)} make regions cleanup that previous were marked asrecovering. Called after all tasks processed
{@link #removeStaleRecoveringRegions(Set)} remove stale recovering. called by{@link MasterFileSystem} after Active Master is initialized
{@link #getLastRecoveryTime()} required for garbage collector and should indicate when the lastrecovery has been made
{@link #checkTaskStillAvailable(String)} Check that task is still there
{@link #checkTasks()} check for unassigned tasks and resubmit them
