> Current the Spark-Module Spark SQL implementation gets records from HBase
> from the driver if there is something like the following found in the SQL.
> rowkey = 123
> The reason for this original was normal sql will not have many equal
> operations in a single where clause.
> Zhan, had brought up too points that have value.
> 1. The SQL may be generated and may have many many equal statements in it so
> moving the work to an executor protects the driver from load
> 2. In the correct implementation the drive is connecting to HBase and
> exceptions may cause trouble with the Spark application and not just with the
> a single task execution
