@Robert Levas I found it...some job from some other scheduler was issuing kdestroy and it was taking away the cache. Thanks for your answers

Fount out that this is available in zkfc logs which will be present in the name node. For some reason these logs are not present in my name node boxes, so probably I need to restart the ZKFC services. Thanks Kumar

I need to know if there was any failover happened on name node services. Where can I get this information. Is there any REST API ?

@Robert Levas forgot to mention that this is sporadic. the script does bunch of HDFS operations. sudo -u user1 bash -c "kinit -R || kinit -k -t ~user1/user1.headless.keytab

I have "klist" written in front of all hdfs commands in my script. When the job starts, it says the credentials are present and valid for next few days. But immediately once the next hdfs command starts it says as follows: "klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_603)" [2017-09-20 08:24:57,335] {bash_operator.py:74} INFO - javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

I am pretty sure disk1 is not mounted to the root partition. I unmounted and mounted back, but this alert is not going away. Has someone faced this issue before ? thanks Kumar
