Subject [jira] [Created] (HIVE-3603) Enable client-side caching for scans on HBase
Date Sun, 21 Oct 2012 18:14:12 GMT
Karthik Ranganathan created HIVE-3603:

             Summary: Enable client-side caching for scans on HBase
                 Key: HIVE-3603
             Project: Hive
          Issue Type: Improvement
            Reporter: Karthik Ranganathan
            Priority: Minor

HBaseHandler sets up a TableInputFormat MR job against HBase to read data in. The underlying
implementation (in 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.
