keyValueSystem.createStore results a directory whose user & group is empty and AccessControlExceptio

[Yuexiang Zhang]

Hi,

My Alluxio version is 1.4.0

When the client runs as a non-root user, e.g. user tom,  keyValueSystem.createStore will result a store directory whose user & group are empty, e.g.

# bin/alluxio fs ls /kvs

drwxr-xr-x                                   0.00B     02-25-2017 19:25:17:631  Directory      /kvs/store1

Then AccessControlException will happen when we write something to it, e.g.  writer.put("a", "aaa"); we 'll get an AccessControlException

alluxio.exception.AccessControlException: Permission denied: user=tom, access=-w-, path=/kvs/store1/part-00000: failed at store1, inode owner=, inode group=, inode mode=rwxr-xr-x

Thanks Yuexiang,

Alluxio KV is currently an experimental feature.

This looks like a bug to me.

Are you running this for fun or will this block you?

Also,  you could create a JIRA ticket on our JIRA system https://alluxio.atlassian.net/ to track this if this is important to you

Thanks Bin,

I just disabled authorization by set alluxio.security.authorization.permission.enabled=false and it's OK now.
