Allen Wittenauer commented on HDFS-13822:
-----------------------------------------

So I'm working on some Yetus bugs when I stumble back into this... mess.

I just noticed the altern code.   It triggers when the 'test-patch' profile is 
set, regardless of when native is set.  This means it runs the clunky antrun 
version of cmake a few extra times during precommits that touch 
hdfs-native-client and any of its parents. 

Let's add this up.

1 x mvn install branch
2 x mvn compile branch
1 x mvn install patch
2 x mvn compile patch

I'm flabbergasted.  Especially so since it doesn't even work correctly.   It's 
still using the same compilers for both compiles.

> libhdfs++ has significantly increased clean build times for the native client 
> on trunk. Problem is that libhdfs++ isn't build in parallel. When I tried to 
> force a parallel build by specifying -Dnative_make_args=-j4, the build fails 
> due to dependencies.
