Ravi Prakash commented on MAPREDUCE-3087:
-----------------------------------------
Ok! So here's what I did. I breakpointed at ContainerLaunch.java:197 (which
basically launches the containers). While execution was suspended, I manually
edited the task.sh to change mr-app.jar!/mrapp-generated-classpath to simply
mr-app.jar.
I had to do this thrice for a simple word-count (once for the AM, once for the
map and once for the reduce I guess). This let me job succeed.
Did MR-2880 simplify the expansion of !/mrapp-generated-classpath, or is this
some cool JAVA classpath trick that I don't know about?
