Tsz Wo Nicholas Sze commented on HDFS-11946:
--------------------------------------------
+1 the patch looks good. The container paths now depends on datanodes as shown
below.

> Ozone: Containers in different datanodes are mapped to the same location

> Key: HDFS-11946

> Project: Hadoop HDFS

>
> This is a problem in unit tests. Containers with the same container name in
> different datanodes are mapped to the same local path location. As a result,
> the first datanode will be able to succeed creating the container file but
> the remaining datanodes will fail to create the container file with
> FileAlreadyExistsException.
