HBase Region Server Heap Configuration


HBase Region Server Heap Configuration

New Contributor

I am using hbase version 1.0 through cloudera (version 5.5.2). I need to benchmark query performance (through phoenix 4.6) on hbase with and without bucket cache.


I have configured java heap size on the region server as 3.5 GB on the cloudera manager console though the region server web ui (server metrics -> Memory tab) shows the max heap to be 1.7. hbase.block.cache.size is configured to be 0.6, is configured to be 0.1 while is configured to be 0.2 so that the blockcache + memstore combination does not exceed 0.8. 
What could be the reason behind the difference shown on the region server web ui?
Appreciate your replies.
