> But, I changed from Spark Cluster 1.5.1 to Spark Cluster 1.4.0, then run the
> job, job complete with Success.
> In Addition, I disable High Availability on HDFS, then run the job, job
> complete with Success.
> So, I think Spark1.5 and higher have bug as the point.
> note: I try these packages in my Cluster, But both of these fail.
> * spark-1.5.1-bin-hadoop2.6.tgz
> * spark-1.5.1-bin-without-hadoop.tgz
> Only *spark-1.4.0-bin-hadoop2.6.tgz* success.
