    Description

      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)
