I have deployed HDP 2.6 with ambari on a 4 node cluster. The deployment went well, but now im not able to perform map reduce jobs.
Whenever i try i get the exeption at 0% of the job:
INFO mapreduce.Job: Job job_1510791427999_0007 failed with state FAILED due to: Application application_1510791427999_0007 failed 2 times due to Error launching appattempt_1510791427999_0007_000002. Got exception: org.apache.hadoop.security.token.SecretManager$InvalidToken: Given NMToken for application : appattempt_1510791427999_0007_000002 is not valid for current node manager.expected : node2.novalocal:45454 found : node3.novalocal:45454
I did some research but i coulnt understand where is the problem or what could be the solution. Can you provide any Help?
