>
> The scenario is like this
> -> A region is getting splitted.
> -> The master is still not processed the split .
> -> Region server goes down.
> -> Split log manager starts splitting the logs and creates the
> recovered.edits in the splitlog path.
> -> CJ starts and deletes the entry from META and also just completes the
> deletion of the region dir.
> -> in hlogSplitter on final step we rename the recovered.edits to come under
> the regiondir.
> There if the regiondir doesnot exist we tend to create and then add the
> recovered.edits.
> Because of this HBCK thinks it to be an orphan region because we have the
> regiondir but with no regioninfo.
> Ideally cluster is fine but we it is misleading.

> Path dstdir = dst.getParent();
> if (!fs.exists(dstdir)) {
> if (!fs.mkdirs(dstdir)) LOG.warn("mkdir failed on " + dstdir);
> }
> }
> fs.rename(src, dst);
> LOG.debug(" moved " + src + " => " + dst);
> } else {
> LOG.debug("Could not move recovered edits from " + src +
> " as it doesn't exist");
> }
> }
> archiveLogs(null, corruptedLogs, processedLogs,
> oldLogDir, fs, conf);
