llap daemon's submitWork: Unsigned fragment not allowed


llap daemon's submitWork: Unsigned fragment not allowed

New Contributor


I experienced this error when submitting a query on a secured cluster (Hadoop 2.7.5 + Hive 2.1.1 + Tez 0.9.1 + llap):

From the log, looks like the fragment was not signed when submitted to llap.

This did not happen when I turned llap off (the cluster is secured; keytabs are provided).

Anyone could let me know how and why this failure happened and any suggestion would be much appreciated. Thanks.
