Colin Patrick McCabe created HDFS-3691:
------------------------------------------
Summary: UserGroupInformation#spawnAutoRenewalThreadForUserCreds
dumps shell output to stdout / stderr
Key: HDFS-3691
URL: https://issues.apache.org/jira/browse/HDFS-3691
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 2.0.1-alpha
Reporter: Colin Patrick McCabe
Priority: Minor
Fix For: 2.2.0-alpha
UserGroupInformation#spawnAutoRenewalThreadForUserCreds tries to renew user
credentials. However, it does this even if the kerberos ticket cache in
question is non-renewable.
This leads to an annoying error message being printed out all the time.
