Partitioning the new volume fdisk /dev/xvdf Formatting the partition mkfs.ext4 /dev/xvdf1 Mounting the partition on directory mount /dev/xvdf1 /datanode Configuring hdfds-site.xml file in slave node of hadoop cluster <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>dfs.data.dir</name> <value>/datanode</value> </property> </configuration> Here datanode is the directory on which the volume is mounted.
