Christopher Tubbs commented on ACCUMULO-3662:
---------------------------------------------
I think we can add a quick check to verify {{$JAVA_HOME/bin/javah}} exists in
the Makefile, right? That should be sufficient to determine if the JAVA_HOME
points to a JDK. After that, we can just assume the JNI headers are in the
include directory. We could check for the JNI headers directly, but that may
not be as platform-independent as checking for the existence of javah.
Do we need to do this check on Darwin also, or just Linux? I mean, can we
assume Darwin has a JDK installed, or no?
> Verify correct looking JAVA_HOME in build_native_library.sh

> JAVA_HOME needs to be set to a valid JDK to run {{build_native_library.sh}}
> successfully. Either it's extracted from the environment or it's set in
> accumulo-env.sh.
> Either way, when it isn't set (or set incorrectly), we should catch this,
> print a warning and exit the script to prevent the deluge 'JNI_EXPORT'
> related error messages.
