fuse-dfs per FD context is not thread safe and can cause segfaults and corruptions
----------------------------------------------------------------------------------

                 Key: HADOOP-4398
                 URL: https://issues.apache.org/jira/browse/HADOOP-4398
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/fuse-dfs
    Affects Versions: 0.19.0
            Reporter: Pete Wyckoff
             Fix For: 0.19.0


this affects dfs_read and dfs_write and dfs_open dfs_release.

people have seen corruptions in 0.18.1 on reads - hadoop-4397.

In 0.19 since there is no global DFS handle, it is slightly different, but the same principles
need to be applied and make the per FD context data (ie ptr to DFS, read buffer, ...) thread
safe.

I can't think of a way to add a reliable test case for this in the current framework, but
should be sure to assert pre/post conditions wherever possible.
