hi [~tgraves] I use 1.3.0 to run. if i donot set SPARK_HOME at every node, i
get the following exception in every executor:
Error from python worker:
/usr/bin/python: No module named pyspark
PYTHONPATH was:
/data/yarnenv/local/usercache/lianhui/filecache/296/spark-assembly-1.3.0-hadoop2.2.0.jar/python
java.io.EOFException
at java.io.DataInputStream.readInt(DataInputStream.java:392)

at org.apache.spark.rdd.RDD.computeOrReadCheckpoint(RDD.scala:277)
at org.apache.spark.rdd.RDD.iterator(RDD.scala:244)
from the exception, i can find that pyspark of the spark.jar in nodeManager
cannot be worked. and i donot know why it is. [~andrewor14] can you help me?
so i think now we should put spark dirs to PYTHONPATH or SPARK_HOME at every
node.

> python support yarn cluster mode requires SPARK_HOME to be set

> Key: SPARK-6506
> URL: https://issues.apache.org/jira/browse/SPARK-6506
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 1.3.0
> Reporter: Thomas Graves
>
> We added support for python running in yarn cluster mode in
> https://issues.apache.org/jira/browse/SPARK-5173, but it requires that
> SPARK_HOME be set in the environment variables for application master and
> executor. It doesn't have to be set to anything real but it fails if its not
> set. See the command at the end of: https://github.com/apache/spark/pull/3976
