Subject Re: Erratic Jenkins behavior
Date Tue, 10 Feb 2015 10:13:31 GMT
Mvn is a dark mystery to us all. I wouldn't trust it not pick up things from other builds if
they ended up published to ~/.m2/repository during the process

I'm sorry, I don't have any insight into this. With regard to
HADOOP-11084, I thought that $BUILD_URL would be unique for each
concurrent build, which would prevent build artifacts from getting
mixed up between jobs. Based on the value of PATCHPROCESS that Kihwal
posted, perhaps this is not the case? Perhaps someone can explain how
this is supposed to work (I am a Jenkins newbie).

Colin
