Xi Fang commented on HIVE-4558:
-------------------------------
The testcase on Windows prints out one new line and one sentence "groups found
for user Administrators". The current method used in QTestUtil.java (i.e.
maskPatterns(String[] patterns, String fname)) can't make an appropriate mask
pattern for this case. I added another method called maskPatternsForWindows(),
specifically for Windows. We can specify a pattern, which may include one line
or multiple lines. For example, in this case, the pattern is composed of one
empty line and one sentence "groups found for user Administrators". Once such a
pattern is found in the *.q.out.orig file, we directly skip this part. This
ensures that "diff" will skip checking the content in output that matches this
pattern.
