> Project: Hive
> Issue Type: Improvement
> Components: HBase Handler

> Assignee: Navis
> Priority: Minor

> HBaseHandler sets up a TableInputFormat MR job against HBase to read data in.
> The underlying implementation (in HBaseHandler.java) makes an RPC call per
> row-key, which makes it very inefficient. Need to specify a client side cache
> size on the scan.
> Note that HBase currently only supports num-rows based caching (no way to
> specify a memory limit). Created HBASE-6770 to address this.
