Description

bash-4.1# bin/hadoop checknative
15/12/14 05:49:34 WARN bzip2.Bzip2Factory: Failed to load/initialize native-bzip2 library system-native, will use pure-Java version

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.util.NativeCodeLoader.buildSupportsIsal()Z
	at org.apache.hadoop.util.NativeCodeLoader.buildSupportsIsal(Native Method)
	at org.apache.hadoop.io.erasurecode.ErasureCodeNative.<clinit>(ErasureCodeNative.java:41)
	at org.apache.hadoop.util.NativeLibraryChecker.main(NativeLibraryChecker.java:98)

It seems to be caused by unhandled exception thrown by NativeCodeLoader.isNativeCodeLoader.

Env: Ubuntu 14.04 LTS
