Do you have the error message from running java? You can use myMapper.sh to
help you debug what is happening and logging it. Stderr of myMapper.sh is
logged and you can get to it. You can run shell commands link find, ls, and
you can probably look at any error messages that java produced whil
Yes, I did, the myMapper.sh is executed, the problem is inside this
myMapper.sh, it calls a java program named myJava, the myJava did not get
executed on slaves, and I shipped myJava.class too.
Thanks,
