Hello,
I am a masters student and working on a PIG-2597 Move grunt from JAVACC to
ANTLR.
I am facing an issue while testing org.apache.pig.test.TestGrunt.java
I am trying to run TestGrunt.java individually using the following command
$ ant -Dtestcase=Testgrunt.java clean test
While running this unit test I am getting an error:
12/08/20 11:00:50 WARN util.MBeans:

------------- ---------------- ---------------
The umask is already set to 0022. I also tried to set permission to
rwxr-xr-x, but it is being reset to rwxrwxr-x every time I run the test.
Could you please suggest me what could be the solution here?
