Sanjay Radia commented on HDFS-593:
-----------------------------------
Lets revist this issue.
When writing the tests for viewfs's trashbin, (see HADOOP-7284), I had to take
into account that
the tests ran on mac or linux boxes or hdfs each of which have different
notions of the home directory.
When this Jira was filed, the proposal was that the home dir is SS config. Made
sense to me.
With viewfs (ie client-side mount table) there is no server side and further
the client side mount table points to multiple file servers. Since viewfs is
configured via config variables it is quite easy to add a config variable for
this. I proposed that in HADOOP-7284 and Todd aggreed.
But I think this topic deserves a fresh look:
* For HDFS, homme-dir is a SS property with a default of /user, for viewfs
determined from viewfs's config, and for localfs, figured out dynamically.
* Home dir is config variable with a default of /user and for viewfs determined
from its config so that it can adapt to mounts of localfs and hdfs.

> This is a sub-task of HADOOP-4952. Currently the Path of user home dir is
> constructed on the client side using convention "/user/$USER". HADOOP-4952
> calls for it to be retrieved from server side.
