Guanghao Zhang commented on HBASE-22709:
----------------------------------------
bq. Will this overload master? We have already put lots of functions into
master...
It only need to list the hdfs directory. And no need to scan meta. And the
rsReports is in-memory.
For the region hole or overlap problem, it will be done in CatalogJanitor. It
already scan meta now. I thought it is fine to add more checking thing in
CatalogJanitor.
> Add a chore thread in master to do hbck checking
