How can this be fixed? I have run hbck -repair a few times but
it doesnt make a diff.
THis is what's reported in hbck log:
java.io.IOException: Region {ENCODED => ff1472457c0dba52ca09f464bf691244, NAME

This is specifically true for Regions metrics such as

Even though the hadoop metrics2 framework allows for "tags' (which are called
dimensions everywhere else) HBase does not take full advantage of that and
instead spews metric

To alleviate the load in read-heavy clusters, one could assign Region servers
