Subject Long running Spark job on YARN throws "No AMRMToken"
Date Tue, 09 Feb 2016 04:34:57 GMT
Hi All,

    A long running Spark job on YARN throws below exception after running
for few days.

yarn.ApplicationMaster: Reporter thread fails 1 time(s) in a row.
org.apache.hadoop.yarn.exceptions.YarnException: *No AMRMToken found* for
user prabhu at org.apache.hadoop.yarn.ipc.RPCUtil.getRemoteException(RPCUti
l.java:45)

Do any of the below renew the AMRMToken and solve the issue

1. yarn-resourcemanager.delegation.token.max-lifetime increase from 7 days

2. Configuring Proxy user:

<property> <name>hadoop.proxyuser.yarn.hosts</name> <value>*</value>
</property>
<property> <name>hadoop.proxyuser.yarn.groups</name> <value>*</value>
</property>

3. Can Spark-1.4.0 handle with fix
https://issues.apache.org/jira/browse/SPARK-5342

    spark.yarn.credentials.file


How to renew the AMRMToken for a long running job on YARN?


Thanks,
Prabhu Joseph
