Zhe Zhang commented on HDFS-9268:
-

The patch LGTM. One minor suggestion is maybe we can fold {{fuseConnect}} into 
{{fuseConnectAsThreadUid}} to avoid bugs of this kind in the future? Seems we 
should always call {{fuseConnect}} with the thread UID anyway.

[jira] [Commented] (HDFS-9268) fuse_dfs chown crashes when uid is passed as -1

Colin Patrick McCabe commented on HDFS-9268:


I don't think {{fuseConnect}} is used anywhere but in fuse_connect.c at this 
point, so it could be made private to that file.

Thanks [~cmccabe] for the clarification. Please see if you want to update the 
patch and make {{fuseConnect}} private. Otherwise +1 on the latest patch.

Hi [~cmccabe], I was going to create a test case for this, but then noticed 
"mvn test" does not run any unit tests of fuse_dfs. Is that right? I understand 
unit-testing this may be hard, but the code base does appear to have test code 
( I did not run it though)

I posted a patch which fixes the root of the problem, I think.  We should be 
using {{fuseConnectAsThreadUid}} instead of {{fuseConnect}}.
