Subject [jira] [Updated] (HADOOP-12638) UnsatisfiedLinkError while checking ISA-L in checknative command.
Date Mon, 14 Dec 2015 12:50:46 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-12638?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kai Sasaki updated HADOOP-12638:
--------------------------------
    Description: 
{code}
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
15/12/14 05:49:34 WARN zlib.ZlibFactory: Failed to load/initialize native-zlib library
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)
{code}

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


Env: Ubuntu 14.04 LTS
