Subject [jira] [Commented] (HADOOP-9162) Add utility to check native library availability
Date Fri, 21 Dec 2012 22:49:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13538496#comment-13538496

Luke Lu commented on HADOOP-9162:

What would be the semantics of InterfaceAudience.Private on a executable main class? The class
name can only be referred in a Hadoop script and not some other scripts?

> Many times, after deploy hadoop or when trouble shooting, we need to check whether native
library(along with native compression libraries) can work properly, and I just want to use
one command to check that, like this:
> hadoop org.apache.hadoop.util.NativeCodeLoader
> and it shows:
> Native library loading test:
> hadoop: false
> zlib:   false
> snappy: false
> lz4:    false
