Binglin Chang updated HADOOP-9162:
----------------------------------
Attachment: HADOOP-9162.v2.patch
new version addressing my previous comments.
As a single main class util, it's hard to add unit test. But I have done some
simple manual test, here is the result.
{code}
decster:~/projects/hadoop-trunk/hadoop-dist/target/hadoop-3.0.0-SNAPSHOT>
bin/hadoop
Usage: hadoop [--config confdir] COMMAND
where COMMAND is one of:
fs run a generic filesystem user client
version print the version
jar <jar> run a jar file
checknative [-a|-h] check native hadoop and compression libraries
availability
distcp <srcurl> <desturl> copy file or directories recursively
archive -archiveName NAME -p <parent path> <src>* <dest> create a hadoop
archive
classpath prints the class path needed to get the
Hadoop jar and the required libraries
daemonlog get/set the log level for each daemon
or
CLASSNAME run the class named CLASSNAME
Most commands print help when invoked w/o parameters.

NativeLibraryChecker [-a|-h]

>
> 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
