Thomas Graves created HDFS-12670:
------------------------------------
Summary: can't renew HDFS tokens with only the hdfs client jar
Key: HDFS-12670
URL: https://issues.apache.org/jira/browse/HDFS-12670
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.8.1
Reporter: Thomas Graves
It looks like the meta inf file for the hdfs token renewer is in the
hadoop-hdfs.jar rather then the hadoop-hdfs-client.jar. This prevents a client
from renewing a token because the service loader doesn't find the DFSClient
Renewer class and falls back to use the TrivialRenewer.
You get an error like:
17/10/16 21:08:15 WARN Token: No TokenRenewer defined for token kind
HDFS_DELEGATION_TOKEN
Exception in thread “main” java.lang.UnsupportedOperationException: Token
renewal is not supported for HDFS_DELEGATION_TOKEN tokens
at
org.apache.hadoop.security.token.Token$TrivialRenewer.renew(Token.java:497)
