Sometime during the last week, someone committed a change to:
that inserted a -m32 in:
This breaks the build on 64-bit systems that do not have 32-bit libraries installed. The change was actually not required as 64-bit support for JNI and JVMs is readily available and installed by default on many 64-bit systems. Removing the flag results in a completed and functional build.
If mandating 32-bit builds is desired, then a better solution would be to provide a configure flag such as -DHADOOP_32bit_MODE, perhaps with a corresponding flag for 64-bit. Regardless, locking the system to 32-bit builds seems a tad extreme.
