Allen Wittenauer resolved HADOOP-10991.
---------------------------------------
Resolution: Cannot Reproduce
This is either:
a) permissions issue in /home/hadoop
b) misconfiguration in hdfs-site.xml
I've run namenode format in many many directories, including /home and not
/home.
It should be noted that changing HADOOP_PREFIX has zero influence on where the
NN fsimage gets created.
Closing as cannot reproduce.
> 'hadoop namenode -format' fails if user hadoop homedir is not under /home

> Key: HADOOP-10991
> URL: https://issues.apache.org/jira/browse/HADOOP-10991
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 2.5.0
> Environment: CentOS 6.5
> Reporter: Yaniv Kaul
> Priority: Minor
> Labels: namenode
>
> Since my homedir is on shared NFS, I couldn't create a user for hadoop on
> /home. Therefore, I've used:
> useradd hadoop --home /hadoop
> which worked well. I've adjusted HADOOP_HOME and friends to match correctly.
