FileNotFoundException while executing spark job - hadoop

Question

I am trying to execute a program on Spark. I have a cluster with a master and two slave nodes. I am receiving the following error during execution.
Exception in thread "main" org.apache.spark.SparkException: Job aborted due to stage failure: Task 3 in stage 4.0 failed 4 times, most recent failure: Lost task 3.3 in stage 4.0 (TID 44, hadoopslave3): java.lang.RuntimeException: java.io.FileNotFoundException: File /home/ubuntu/hadoop/hadoop-te/dl4j/1485860107978_-4ccc8c8/0/data/dataset_4-4ccc8c8_68.bin does not exist
Driver stacktrace is as follows:

However, I can see all the dataset objects (.bin files) created on the HDFS. Any suggesstions ?

Answer 1

Since you have a cluster with "two slave nodes" set up: do you also have a Hadoop filesystem set up? If not, then that's your issue.
The example you're linking to, when using a non-local cluster, transfers references to datasets using Hadoop. The behavior of this example has been made more predictable (with a big error message) in release 0.8.0.
