stack commented on HBASE-21025:
-------------------------------
Looks good. For the cache, if a table is removed, we for sure clear its entry
in the cache? Should the cache be soft reference? If making new patch, change
name from private final ConcurrentMap<TableName, TableState.State> tn2State =
new ConcurrentHashMap<>(); to tableName2State.
Yeah, this is important change. We need it bad.
