This is line 119 of RegionReplicaFLushHandler
https://github.com/apache/hbase/blob/c2af2b3c0de938f2c2d094860f33e31177d197ea/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/RegionReplicaFlushHandler.java#L119
So the problem is that we get a TableNotFoundException while checking
whether table is disabled, where we should quit the loop but we just throw this
exception out and cause problem.
This PR catched the exception of admin.isTableDisabled, if it is
TableNotFoundException, we just quit, otherwise we will still retry, instead of
aborting the region server.
