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

The scenario this issue is concerned is not single node deployment.

>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.99.0
>            Reporter: Ted Yu

> HMaster ctor calls HRegionServer ctor which calls CacheConfig ctor where CacheConfig.instantiateBlockCache()
would create BlockCache.
> This happens even if Master is configured not to host regions.
> This was observed when I tried to answer question from the thread titled:
> 'The default hbase.regionserver.info.port doesn't work'
