Description

When native build hadoop-common-project with IBM java using command like:
mvn package -Pnative
it will exist the following errors.
[exec] – Configuring incomplete, errors occurred!
[exec] JAVA_HOME=, JAVA_JVM_LIBRARY=/home/louis/ibm-java-i386-60/jre/lib/i386/classic/libjvm.so
[exec] JAVA_INCLUDE_PATH=/home/louis/ibm-java-i386-60/include, JAVA_INCLUDE_PATH2=JAVA_INCLUDE_PATH2-NOTFOUND
[exec] CMake Error at JNIFlags.cmake:113 (MESSAGE):
[exec] Failed to find a viable JVM installation under JAVA_HOME.
[exec] Call Stack (most recent call first):
[exec] CMakeLists.txt:24 (include)

The reason is that IBM java uses $JAVA_HOME/include/jniport.h instead of $JAVA_HOME/include/jni_md.h in non-IBM java.

[exec] make[2]: *** [test_libhdfs_ops] Error 1
[exec] make[1]: *** [CMakeFiles/test_libhdfs_ops.dir/all] Error 2
[exec] make: *** [all] Error

The reason is libjvm.so need libdl when linking.
