Chris Nauroth updated HDFS-6326:
--------------------------------
Attachment: HDFS-6326.4.patch
Here is patch v4 incorporating the feedback mentioned in the last several
comments.
While fixing the web UI, I also noticed that the logic for printing 't' vs. 'T'
for the sticky bit was incorrect. Due to the way the for loop works, this was
always checking the sticky bit itself instead of the other execute bit. At the
point where the check is performed, the sticky bit is always on anyway, so it
always chose to print 't'. I fixed this bug too.
