--------------------------------------
Summary: No need to instantiate BlockCache for master which not
carry table
Key: HBASE-21290
URL: https://issues.apache.org/jira/browse/HBASE-21290
Project: HBase
Issue Type: Improvement
Reporter: Guanghao Zhang
Assignee: Guanghao Zhang
In our production clusters, we use different jvm config for master/regionserver
but use same hbase-site.xml for master/regionserver. And master has a small
heap/offheap config. So the regionserver's hbase.bucketcache.size is not
suitable for master. I thought we don't need to instantiate BlockCache for
master which not carry table.
