Subject [jira] [Created] (AMBARI-2219) HDFS install results in Invalid hostname exception during namenode start

Trevor McKay created AMBARI-2219:
------------------------------------

             Summary: HDFS install results in Invalid hostname exception during namenode start
                 Key: AMBARI-2219
                 URL: https://issues.apache.org/jira/browse/AMBARI-2219
             Project: Ambari
          Issue Type: Bug
          Components: agent, controller
    Affects Versions: 1.3.0
         Environment: Fedora 16 server
RHEL 6.2 or 6.3 agent
Installing a single machine cluster with HDFS and mapreduce
            Reporter: Trevor McKay


Very reproducible for me, using snapshot builds of trunk and freshly provisioned agent machines
(reusing the same server after ambari-reset)

The HDFS install/start/test fails on starting the namenode with this error:

notice: /Stage[2]/Hdp-hadoop::Namenode/Hdp-hadoop::Namenode::Create_app_directories[create_app_directories]/Hdp-hadoop::Hdfs::Directory[/mapred]/Hdp-hadoop::Exec-hadoop[fs
-mkdir /mapred]/Hdp::Exec[hadoop --config /etc/hadoop/conf fs -mkdir /mapred]/Exec[hadoop
--config /etc/hadoop/conf fs -mkdir /mapred]/returns: 13/05/29 13:14:54 WARN fs.FileSystem:
"null" is a deprecated filesystem name. Use "hdfs://null/" instead.

Is this a configuration error?  Something wrong in the agent?  Something erroneous sent from
the server?
