> Project: Hadoop HDFS
> Issue Type: Bug
> Components: security
> Affects Versions: 0.24.0
> Reporter: Todd Lipcon
>
> 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
