-------------------------------------
Summary: Failing to launch jobs on Spark on YARN with Hadoop 2.5.0 or later
Key: SPARK-4267
URL: https://issues.apache.org/jira/browse/SPARK-4267
Project: Spark
Issue Type: Bug
Reporter: Tsuyoshi OZAWA
Currently we're trying Spark on YARN included in Hadoop 2.5.1. Hadoop 2.5 uses protobuf 2.4.1 so I compiled with protobuf 2.5.1 like this:
{code}
./make-distribution.sh --name spark-1.1.1 --tgz -Pyarn -Dhadoop.version=2.5.1 -Dprotobuf.version=2.5.0
{code}
Then Spark on YARN cannot fail to run with NPE.
{code}
$ bin/spark-shell --master yarn-client
scala> sc.textFile("hdfs:///user/ozawa/wordcountInput20G").flatMap(line => line.split(" ")).map(word => (word, 1)).persist().reduceByKey((a, b) => a + b, 16).saveAsTextFile("hdfs:///user/ozawa/sparkWordcountOutNew2");
