> If region splitting is failed in the state of
> JournalEntry.CLOSED_PARENT_REGION
> It will be rollback as the following steps:
> {code}
> 1.case CLOSED_PARENT_REGION:
> this.parent.initialize();
> break;
> 2.case CREATE_SPLIT_DIR:
> this.parent.writestate.writesEnabled = true;
> cleanupSplitDir(fs, this.splitdir);
> break;
> 3.case SET_SPLITTING_IN_ZK:
> if (server != null && server.getZooKeeper() != null) {
> cleanZK(server, this.parent.getRegionInfo());
> }
> break;
> {code}
> If this.parent.initialize() throws IOException in step 1,
> If check filesystem is ok. it will do nothing.
> However, the parent region is on service now.
