Anoop Sam John commented on HBASE-14046:
----------------------------------------
When this issue came, configured hbase.bucketcache.bucket.sizes to non default
values? Seeing the code in converting long offset into an int baseOffset and
one byte value, we have expectation on the bucket sizes. It has to multiple of
1024.. For other values seems we will get incorrect results.. Did not try to
reproduce a -ve case.
