> 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
