Franjo Markovic commented on HADOOP-10133:
------------------------------------------
Yes, both variables had been set.
I have not been working on this for a while (gave up on windows version, as
both cygwin and "direct" version had a host of different issues).
This particular issue I was able to pinpoint as a problem in variable
declarations/initialization in util.Shell.java.
This line:
private static String HADOOP_HOME_DIR = checkHadoopHome();
is missing a "final" keyword, as "final" variables are initialized before
non-final ones, resulting that (in this case) HADOOP_HOME_DIR was still Null at
the time of WINUTILS variable initialization.
Interesting thing though is that this particular issue does not appear on
non-cygwin setup - must have had some extra patch somewhere.
