Hi @venkatsambath @Shelton ,

 

As you said I deleted the cache directories and tried again. But still facing the same issue, Find below error logs and directory structures.

 

 

Error Logs:

Re: Yarn jobs are failing after enabling MIT-Kerberos

Expert Contributor

These are 2 separate issues

 

ERROR1:

Did you delete till/disk{1,2,3,4,5}/yarn/nm/usercache/mcaf or you deleted till /disk{1,2,3,4,5}/yarn/nm/usercache/

 

If you had deleted till /disk{1,2,3,4,5}/yarn/nm/usercache/ then please restart all the nodemanagers.

If not, Can you please let me know How many nodemanagers do you have in this cluster? Can you run 

namei -l /disk{1,2,3,4,5}/yarn/nm/usercache/ across all those machines?

 

Please paste your result with "Insert or code sample" option in the portable so that it will has better readablity

 

ERROR2:

Mar26 11:36:00,863 main com.class.engineering.portfolio.dmxsloader.main.DMXSLoaderMain: org.apache.hadoop.hbase.client.RetriesExhaustedException thrown: Can't get the location

 

a. The machine from which you are submitting this job - Does it have hbase gateway installed in it? If not can you run it from a machine which has hbase gateway

b. Also since you said this job worked from hbase user and not mcaf - Have you attempted to grant permission to mcaf to the respective table which you are trying to access? https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/cdh_sg_hbase_authorization.html#top... has the steps

c. What is the error you see in HMaster logs during the exact timestamp you notice this error in job?

a. Yes, the hbase gate way is available in the same server.

b. Actually its not worked with hbase user.

And i have granted the permissions to mcaf  through hbase shell like below,

 

hbase(main):004:0> grant 'mcaf', 'RWXC' , 'TABLE1'
0 row(s) in 0.6570 seconds

hbase(main):005:0> user_permission 'TABLE1'
User Namespace,Table,Family,Qualifier:Permission
mcaf default,TABLE1,,: [Permission: actions=READ,WRITE,EXEC,CREATE]
1 row(s) in 0.3960 seconds

hbase(main):006:0> grant 'mcaf', 'RWXC' , 'TABLE2'
0 row(s) in 0.5780 seconds

hbase(main):007:0> user_permission 'TABLE2'
User Namespace,Table,Family,Qualifier:Permission
mcaf default,TABLE2,,: [Permission: actions=READ,WRITE,EXEC,CREATE]
1 row(s) in 0.4060 seconds

 

c. I am not find any error or warn messages in HMaster logs while i am querying.

 

After granting the permissions i have tested my application job and seeing same error messages like above.

 

Please revert back.

Re: Yarn jobs are failing after enabling MIT-Kerberos

Hi @venkatsambath 

 

One problem is resolved, I mean to say i am able to run sample yarn job.

 

Found that one of server having some permission issue and deleted /disk(1,2,3,4,5)/yarn/nm directory and restarted the nodemanager and ran yarn job.

Its worked.

 

And i tried our application related job and this time getting some different error's, 

This job i am running in hostname001 and getting below error and seeing some connection failure to hostname003 server.

Re: Yarn jobs are failing after enabling MIT-Kerberos

The call to this region server 1.1.1.1:60020 is getting closed instantly

Caused by: org.apache.hadoop.hbase.exceptions.ConnectionClosingException:
Call to hostname003.enterprisenet.org/1.1.1.1:60020 failed on local exception: org.apache.hadoop.hbase.exceptions.ConnectionClosingException: Connection to hostname003.enterprisenet.org/1.1.1.1:60020 is closing. Call id=4045, waitTime=2

1. Is there any hbase-site.xml that is bundled with your application jar?

2. If yes, Can you rebuild the jar with latest hbase-site.xml from /etc/hbase/conf/

3. I am not sure if server is printing any ERROR but it will be worth to check, what exactly is happening on RS logs in node hostname003.enterprisenet.org

at the time  2020 Mar 27 01:18:16 (i.e when the connection from client is closed)

Hello @Shelton,

 

There is no logs generated on that time interval.

But i will check for yourquestions with my team and get back to you.

Thanks for responding.

Re: Yarn jobs are failing after enabling MIT-Kerberos

Hello @Shelton @venkatsambath 

 

Hope you all doing good.

None of the configuration files are bundled with our jars and they use our latest updated config files in the cluster only.

What i am missing here ?

what could be the reason for failing after enabling Kerberos ?

 

Please do the needful.

Vinod
