Instead of using ${hadoop.tmp.dir}/dfs/data you give multiple directories with
absolute paths.Just try as
follows:<property><name>hadoop.data.dir</name><value>/home1/user1/dir1,/home2/user2/dir2</value></property>This
will allow HDFS to write data into all specified directories.

dfs.data.dir
${hadoop.tmp.dir}/dfs/dataDetermines where on the local filesystem an DFS data
node should store its blocks. If this is a comma-delimited list of directories,
then data will be stored in all named directories, typically on different
devices. Directories that do not exist are ignored.

Hi Tariq,
What is the default value of dfs.data.dir? My hdfs-site.xml doesnt have this
value defined. So what is the default value?
Thanks,
Raj

Hello Raj,
Although the way which Mustaqeem has told is correct, there is more
appropriate way to do this. Add the "dfs.data.dir" property in your
hdfs-site.xml and give the "path you want to use for HDFS data storage" as its
value. The directory pointed by hadoop.tmp.dir also contains the metadata and
some other temporary files, so it's always better to have a dedicated location
to store the actual HDFS data.
Warm Regards,
Tariq

Thanks Mustaqeem.
hadoop.tmp.dir - Can this store HDFS files? I mean - is there any difference in
files from the one we create under HADOOP_HOME.

You can mentioned the "hadoop.tmp.dir" property in the core-site.xml as -
<property>
<name>hadoop.tmp.dir</name>
<value>/app/software/app1</value>
</property>
"/app/software/app1" will be used as location for storing the hdfs files.

Hi,
I have a one node Hadoop cluster for my POC. The HADOOP_HOME is under a
directory
/usr/home/hadoop
I dont have much space on /usr and want to use other accounts/applications
storage which are located at /app/software/app1 etc.,
How can I use the /app/software/app1 location for my HDFS files and storage. Is
it possible? Please advise.
Thanks,
Raj
