Meethu Mathew created ZEPPELIN-2141:
---------------------------------------
Summary: sc.addPyFile("hdfs://path/to file) in zeppelin causing
UnKnownHostException
Key: ZEPPELIN-2141
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2141
Project: Zeppelin
Issue Type: Bug
Components: pySpark
Affects Versions: 0.6.0
Reporter: Meethu Mathew
Priority: Minor
In the documentation of sc.addPyFile(0 its is mentioned that "
Add a .py or .zip dependency for all tasks to be executed on this SparkContext
in the future. The path passed can be either a local file, a file in HDFS (or
other Hadoop-supported filesystems), or an HTTP, HTTPS or FTP URI"
But when I added an HDFS path in the method in zeppelin, it results in the
following exception:
Py4JJavaError: An error occurred while calling
z:org.apache.spark.api.python.PythonRDD.runJob.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in
stage 0.0 failed 4 times, most recent failure: Lost task 0.3 in stage 0.0 (TID
3, demo-node4.flytxt.com): java.lang.IllegalArgumentException:
java.net.UnknownHostException: flycluster
Spark version used is 1.6.2. The same command is working fine with pyspark
shell and hence I think something is wrong with Zeppelin
