Colin Patrick McCabe commented on HDFS-7254:
--------------------------------------------
{code}
DataNode supports hot swappable drives. The user can add or replace HDFS data
{code}
Should be "the Datanode"
{code}
* The user installs the new hard drives, formats them and mounts them
appropriately. Optional.
{code}
This seems a bit confusing. Surely formatting and mounting appropriately is
not optional? Maybe this should be described as "If there are new storage
directories, the user should format them and mount them appropriately."
The rest looks good.
