Steve Loughran commented on HADOOP-10530:
-----------------------------------------
Status
# if you comment out the jenkins script that sets up JAVA_HOME and adds it to
the path, java home is set to JDK7 and the patch rules take.
# but make is failing with "zconf.h" not in the INCLUDE.

This is clearly utterly impossible and can't happen —but it is. Perhaps the
JAVA_HOME/include dir is different in a way that causes problems.
