------------------------------------

             Summary: BLOCKCACHE in schema descriptor seems not aptly named
                 Key: HBASE-11007
                 URL: https://issues.apache.org/jira/browse/HBASE-11007
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.94.18
            Reporter: Varun Sharma
            Assignee: Varun Sharma
            Priority: Minor


Hi,

It seems that setting BLOCKCACHE key to false will disable the Data blocks from being cached
but will continue to cache bloom and index blocks. This same property seems to be called cacheDataOnRead
inside CacheConfig.

Should this be called CACHE_DATA_ON_READ instead of BLOCKCACHE similar to the other CACHE_DATA_ON_WRITE/CACHE_INDEX_ON_WRITE.
We got quite confused and ended up adding our own property CACHE_DATA_ON_READ - we also added
some unit tests for the same.

What do folks think about this ?

Thanks
Varun
