Subject [jira] [Created] (HADOOP-9162) Add utility to check native library availability
Date Thu, 20 Dec 2012 16:27:14 GMT
Binglin Chang created HADOOP-9162:

             Summary: Add utility to check native library availability
                 Key: HADOOP-9162
                 URL: https://issues.apache.org/jira/browse/HADOOP-9162
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Binglin Chang
            Assignee: Binglin Chang
            Priority: Minor

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
