    Affects Versions: 1.2.0
            Reporter: ulysses you


The configuration error in two method. First is ok, and second is wrong.

{code:java}
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])

and the log:

I'm sure that I have upload jar with spark cmd -jars.
Is this a bug?
