Subject Re: Running Spark on Yarn-Client/Cluster mode

Hi Ashesh

You might be experiencing problems with the virtual memory allocation.
Try grepping the yarn-hadoop-nodemanager-*.log (found in
$HADOOP_INSTALL/logs) for 'virtual memory limits'
If you se a message like
---------
WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainersMonitorImpl:
Container [pid=5692,containerID=container_1460451108851_0001_02_000001]
is running beyond virtual memory limits. Current usage: 248.7 MB of 1
GB physical memory used; 2.1 GB of 2.1 GB virtual memory used. Killing
container.
---------
thats you problem.

You can solve it setting the yarn.nodemanager.vmem-pmem-ratio to a
higher ratio in yarn-site.xml like this:
----------
 <property>
   <name>yarn.nodemanager.vmem-pmem-ratio</name>
    <value>5</value>
    <description>Ratio between virtual memory to physical memory when
setting memory limits for containers</description>
  </property>
----------

You can also totally disable the vmem-check.

See https://issues.apache.org/jira/browse/YARN-4714 for further info
