Wei-Chiu Chuang commented on HADOOP-12692:
------------------------------------------
I am not sure...the timestamp format does not match the error message.
I found this https://issues.apache.org/jira/browse/MENFORCER-118
Apparently there was a similar bug in maven enforcer, but it was resolved in
maven enforcer 1.1, and upstream Jenkins uses 1.3.
Also, this failure looks intermittent. But we (at Cloudera) have also observed
the same failure symptom on our internal Jenkins running trunk branch. I can
see some times timestamped hadoop-auth jars are created under the local .m2/
repository.
