Hello, Sorry to reopen this topic. I had setup yarn couple of months ago and cant seem to replicate this now.
I see that I have done everything listed here http://samza.apache.org/learn/tutorials/0.7.0/run-in-multi-node-yarn.html I see this error on the application side Application application_1426115467623_0492 failed 2 times due to AM Container for appattempt_1426115467623_0492_000002 exited with exitCode: -1000 due to: java.lang.ClassNotFoundException: Class org.apache.samza.util.hadoop.HttpFileSystem not found .Failing this attempt.. Failing the application. I see that /home/hadoop/hadoop-2.5.2/share/hadoop/hdfs/lib/samza-yarn_2.10-0.8.0.jar has that particular class 1739 Tue Nov 25 10:51:40 PST 2014 org/apache/samza/util/hadoop/HttpFileSystem$$anonfun$getFileStatus$1.class 1570 Tue Nov 25 10:51:40 PST 2014 org/apache/samza/util/hadoop/HttpFileSystem$$anonfun$initialize$1.class 1597 Tue Nov 25 10:51:40 PST 2014 org/apache/samza/util/hadoop/HttpFileSystem$$anonfun$open$1.class 1797 Tue Nov 25 10:51:40 PST 2014 org/apache/samza/util/hadoop/HttpFileSystem$$anonfun$open$2.class 9549 Tue Nov 25 10:51:40 PST 2014 org/apache/samza/util/hadoop/HttpFileSystem.class I see that env is set right: HADOOP_YARN_HOME=/home/hadoop/hadoop-2.5.2 HADOOP_CONF_DIR=/home/hadoop/hadoop-2.5.2/conf Wondering if I am missing anything... - Shekar
