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

             Summary: Make pubic convertScanToString for Spark
                 Key: HBASE-15223
                 URL: https://issues.apache.org/jira/browse/HBASE-15223
             Project: HBase
          Issue Type: Improvement
            Reporter: Jerry He


One way to access HBase from Spark is to use newAPIHadoopRDD, which can take a TableInputFormat
as class name.  But we are not able to set a Scan object in there, for example to set a HBase
filter.

In MR,  the public API TableMapReduceUtil.initTableMapperJob() or equivalent is used which
can take a Scan object.  But this call is not used in Spark conveniently. 

We need to make the TableMapReduceUtil.convertScanToString() public.
So that a Scan object can be created, populated and then convert to the property and used
by Spark.  They are now package private.
