[jira] [Commented] (HADOOP-8884) DEBUG should be WARN for DEBUG util.NativeCodeLoader: Failed to load native-hadoop with error: java.lang.UnsatisfiedLinkError

    [ https://issues.apache.org/jira/browse/HADOOP-8884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14965657#comment-14965657 ] 

Anthony Rojas commented on HADOOP-8884:
---------------------------------------

I believe it's still a useful feature to have a warning message when native libraries are enabled but not available, although there's some additional work needed to properly implement this.

> Recommending to change the following debug message and promote it to a warning instead:
> 12/07/02 18:41:44 DEBUG util.NativeCodeLoader: Failed to load native-hadoop with error: java.lang.UnsatisfiedLinkError: /usr/lib/hadoop/lib/native/libhadoop.so.1.0.0: /lib64/libc.so.6: version `GLIBC_2.6' not found (required by /usr/lib/hadoop/lib/native/libhadoop.so.1.0.0)
