> if you add a space between the storage type and file URI then datanodes fail
> during startup.
> Here is an example of "mis-configration" that leads to datanode failure.
> {code}
> <property>
> <name>dfs.datanode.data.dir</name>
> <value>
> [DISK] file://tmp/hadoop-aengineer/disk1/dfs/data
> </value>
> </property>

> Here is the "fixed" version. Please *note* the lack of space between \[DISK\]
> and file URI

> <name>dfs.datanode.data.dir</name>
> <value>
> [DISK]file://tmp/hadoop-aengineer/disk1/dfs/data
