Allen Wittenauer commented on HADOOP-12130:
-------------------------------------------
bq. The "either" looks superfluous, I think?
Yes. I was in the process of checking to see if there was another way we
exposed maven/ant args and never got back to it. lol (The answer is no, btw.
Should probably JIRA that.)
bq. consider "HINT: We recommend you make the ..."
I come from the 'school of writing' where 'you' is bad form so always try to
avoid it as best I can. But yeah, this would probably be better. Actually,
just changing this to 'recommended' fixes it too.
bq. this is probably a topic for later, but what if we're running a C/C++
project in Maven? would that just always have BUILD_NATIVE? Should this say
something like "has requested non-Java code" or is it specifically looking for
JNI bindings?
You're correct that BUILD_NATIVE isn't just JNI, given it also builds non-JNI
libraries in Hadoop. I spent quite a bit of time puzzling over what to write
here. I think non-Java code covers to much (e.g., scala and clojure). I'll
change it to "non-JVM-based".
bq. Is "javac" considered a test? if not, what version gets used to build the
classes? to do the install step?
Yes, javac is considered a test. install is done with JAVA_HOME so that the
repo has the default Java bytecodes.
