It depends what you want to change:
If you want just to add additional disks in all nodes follow this:
Best way to create partitions like /grid/0/hadoop/hdfs/data - /grid/10/hadoop/hdfs/data and mount them to new formatted disks (its one of recommendation parameters for hdfs data mounts but you can change it):
/dev/sda1 /grid/0 ext4 inode_readahead_blks=128,commit=30,data=writeback,noatime,nodiratime,nodev,nobarrier 0 0
/dev/sdb1 /grid/1 ext4 inode_readahead_blks=128,commit=30,data=writeback,noatime,nodiratime,nodev,nobarrier 0 0
/dev/sdc1 /grid/2 ext4 inode_readahead_blks=128,commit=30,data=writeback,noatime,nodiratime,nodev,nobarrier 0 0
After that just add all partitions paths in hdfs configs like:
/grid/0/hadoop/hdfs/data,/grid/1/hadoop/hdfs/data,/grid/2/hadoop/hdfs/data
But dont delete existed partition from configuration because you will lost data from block which stored in /hadoop/hdfs/data.
Path dont really matter just keep them separately and dont forget to make re-balance between disks.
