spark over hbase snapshot

1.
val hConf = HBaseConfiguration.create()
// ignore some config

val hBaseRDD = sc.newAPIHadoopRDD(hConf,
      classOf[TableSnapshotInputFormat],
      classOf[org.apache.hadoop.hbase.io.ImmutableBytesWritable],
      classOf[org.apache.hadoop.hbase.client.Result])
2.
val hConf = HBaseConfiguration.create()
val job = Job.getInstance(hConf)
val hBaseRDD = sc.newAPIHadoopRDD(job.getConfiguration,
      classOf[TableSnapshotInputFormat],
      classOf[org.apache.hadoop.hbase.io.ImmutableBytesWritable],
      classOf[org.apache.hadoop.hbase.client.Result])
