> We are facing problem creating online snapshot of our HBase table. The table contains 20TB data and receiving ~10000 writes per second. The snapshot creating failing intermittently with error that some hfile missing, see the detailed output below. Once we locate the region server hosting the region and restart the region server, snapshot creation succeeds. It seems the missing hfile removed due to minor compaction, but region server still holds the pointer to the file.
