    Description

      If I call "bin/hdfs fetchdt /tmp/mytoken" without a "--renewer foo" argument, then it will throw a NullPointerException:

      Exception in thread "main" java.lang.NullPointerException
      at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getDelegationToken(ClientNamenodeProtocolTranslatorPB.java:830)

      this is because getDelegationToken is being called with a null renewer
