> Key: HDFS-455
> URL: https://issues.apache.org/jira/browse/HDFS-455
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: data-node, name-node
> Affects Versions: 0.20.1, 0.21.0
> Reporter: Michele Catasta
> Assignee: Michele Catasta
> Priority: Minor
> Attachments: HDFS-455.patch, hdfs-455.txt
>
>
> The following configuration causes problems:
> <property>
> <name>dfs.data.dir</name>
> <value>/mnt/hstore2/hdfs, /home/foo/dfs</value>
> </property>
> The problem is that the space after the comma causes the second directory for
> storage to be " /home/foo/dfs" which is in a directory named <SPACE> which
> contains a sub-dir named "home" in the hadoop datanodes default directory.
> This will typically cause the user's home partition to fill, but will be very
> hard for the user to understand since a directory with a whitespace name is
> hard to understand.
> (ripped from HADOOP-2366)
