Y. SREENIVASULU REDDY commented on HBASE-13320:
-----------------------------------------------
[~ram_krish]
*hbase.bucketcache.size* this configuration will use when we configured this
*hbase.bucketcache.ioengine*
In my case *hbase.bucketcache.ioengine=heap*
then if configure *hbase.bucketcache.size=0*
then regionserver is failing with the following exception.
