Description

On hbase UI, we can get the details of storefiles in region region by accessing region.jsp.

However, When hbase table enables the region replication, the replica region may reference deleted storefile due to it dosen't refresh in a timely manner, so in this case, we would get FNFE when openning the region.jsp of the region.
