Robert Joseph Evans commented on MAPREDUCE-3819:
------------------------------------------------
>From looking at the code there appear to be a few different possibilities here.
# the protocol class is null.
# SecurityUtil.securityInfoProviders is some how not loading the
AnnotatedSecurityInfo class.
# the protocol class is not annotated correctly.
# the key returned by the annotation is not set.
One and Three seem very unlikely, because that code has worked before. Two
also seems very unlikely because the AnnotatedSecurityInfo class and the config
file for the ServiceLoader is in the same jar as SecurityUtils itself. Found
also seems unlikely because the NodeManagers would in theory use the same
config and are able to talk to the NN, but this is the most likely culprit.
Especially because the RM really does not interact with HDFS at all except here
to renew tokens, so if it were misconfigured then the rest of the RM could keep
working just fine.
@Ramya,
Could you please verify that the following is set in your resource manager
configuration "dfs.namenode.kerberos.principal"
> Exception while renewing delegation token
