INLINE COMMENTS
  src/main/java/org/apache/hadoop/hbase/master/ProcessServerShutdown.java:65 Could we write a one-line comment about the state? I think ABORT means there is no need to split any logs, right?
  src/main/java/org/apache/hadoop/hbase/master/ProcessServerShutdown.java:331 Might be missing something here... this break will just cause the operation to return as if it succeeded, but log splitting is still in progress right? We would then proceed to open the regions without ensuring this is completed?

  Maybe we need:
  this.requeue();
  return false;

> When one region server goes down, the master will shutdown the region server and split its log.
> However, splitting log is a blocking call and it would take some time.
> If more than one region server go down, the master will split its log one by one, which is not efficient.
> Since we have the distributed log split, we could split these logs from the dead servers in parallel.
