Thanks @sodonnell!

 

The permissions problem had been solved, but now I get a new error -

org.apache.hadoop.yarn.exceptions.InvalidAuxServiceException: The auxService:mapreduce_shuffle does not exist

 

part of the error (I think it's too long to post here):

Re: I run a Hadoop job, but it got stucked and nothing is happening

Cloudera Employee

Can you check your /etc/hadoop/conf/yarn-site.xml and ensure the following two parameters are set:

 

  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>

  <property>
    <name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
    <value>org.apache.hadoop.mapred.ShuffleHandler</value>
  </property>

Thank you very much @sodonnell!

Hey, thanks for the post.

Adding these two services should fix the auxillary service exception issue. Dont forget to restart the yarn services.

Thanks!

I am facing similar issue. I have a new installation of Cloudera and i am trying to run a simple Map reduce Pi Example. The job gets stuck at the map 0% and reduce 0% step as shown below.

18/10/16 12:33:31 INFO mapreduce.Job:  map 0% reduce 0%

I made multiple config changes, but cannot find a solution for this. The only error i could trace was in the nodemanager log file as below :

ERROR org.apache.hadoop.yarn.server.nodemanager.NodeManager: RECEIVED SIGNAL 15: SIGTERM

I tried checking various properties discussed in this thread, but i still have that issue. Can someone please help in solving this issue? Please let me know what all details i can provide.
