This is the second time. Couple of weeks back someone changed the hadoop hudson job configuration that the Dversion=$BUILD_ID, which caused a confusion and all the maven artifact publishing task failed. This week all the hadoop patch queue is stuck as the Hadoop-Patch-h1.grid.sp2.yahoo.net job on hudson went missing. ( I ve just re-created this job).
If someone wants to make some changes to the hudson hadoop jobs please contact me, I will be more than happy to help you out. Thanks, Giri
