Thx. BTW, it seems that the output format (subclass of org.apache.hadoop.mapred.OutputFormat) of MR job can only be a file. Can we define our own file format which hbase clients can access?
My goal is to implement filter-enabled table scanner which runs by multi-process clients using MR. I'm trying to leverage MR since the ClientScanner class of HTable sequencially access Hregion and thus involves multiple round trips btw servers and clients.
