Sowmya Ramesh commented on FALCON-1595:
---------------------------------------
[~bvellanki]: What is the root cause for this issue? Why doesn't relogin done
in AuthenticationInitializationService handle this case ? I am trying to
understand if its one off case where token is just expiring and we try to dole
out FS just before relogin. In that case similar to
checkTGTAndReloginFromKeytab shouldn't we relogin if its close to expiry and
not wait till its expired which is the current implementation.

> In a kerberos secured cluster where the Kerberos ticket validity is one day,
> Falcon server eventually lost the ability to read and write to and from HDFS.
> In the logs we saw typical Kerberos-related errors like "GSSException: No
> valid credentials provided (Mechanism level: Failed to find any Kerberos
> tgt)".
