Shen Yinjie updated YARN-7425:
------------------------------
Description:
we have a secure hadoop cluster with namenode federation.
submit job fails after kerberos TGT maxLifeTime expired(default 24h), client
log shows" failed to renew token: HDFS_DELEGATION_TOKEN...".
check rm log, found rm tgt is expired but not triggers relogin(),just retry and
fail...
(rm log see screenshot)
digging in code:
when rm tries to renewToken(),
UserGroupInformation.getLoginUser()="rm",
but UserGroupInformation.getCurrentUser()="testUser".
this causes Client.shouldAuthenticateOverKrb() returns false, thus cant trigger
reloginFromKeytab() or reloginFromTicketCache().
