All, In the interest of learning more about Tez internals I am trying to debug a running installation on a cluster. However, I am having trouble matching the source on my local machine with the jars on the cluster, my source seems to be off by three lines, making debugging impossible.
I installed HDP 2.1 and Tez as instructed in these docs http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.1/bk_installing_manually_book/content/rpm-chap1.html All the jars in the /usr/lib/tez directory are stamped with the following suffix: 0.4.0.2.1.2.0-402. I assume the first three integers are for the Tez version and the rest are the Hadoop version. A "yum list installed | grep tez" returns the same version stamp. Locally, I have checked out the Tez source and updated to the branch-0.4.0-incubating branch. That branch has rc0 and rc1 tags, the difference between which does not really touch any source files, so I don't think it matters to which rc I update my source. Despite updating to what I think the right version is, my DAGAppMaster.java class is off by three lines with the jars on the cluster. I am attaching my debugger to the AppMaster JVM. Any help would be much appreciated! -- Anton
