Guanghao Zhang commented on HBASE-22709:
----------------------------------------
bq. It runs once an hour?
Yes. It need to scan all hdfs dir. So I thought no need to run it frequently.
bq. Can operator ask to run it?
Good idea.
bq. I'm working on a patch to beef up CatalogJanitor so when it scans on its
five minute interval, it reports on holes, overlaps, and unknown servers.
Great. The patch here only handle the orphan regions on RegionServer or on HDFS
and the inconsistent regions.
> Add a chore thread in master to do hbck checking
