Ilya Maykov commented on HADOOP-10359:
--------------------------------------
[~hadoopqa] As far as I know, the build bot doesn't currently build native
libraries on Mac OS X (if it builds anything on Mac OS X), so there are no
automated tests that I could add to test this change.
Manual testing performed:
- built libhadoop.dylib on Mac OS X (requires this patch and the patch for
HADOOP-9648)
- run "hadoop checknative" to verify that bzip2 compression is using the native
code:
{{$ hadoop checknative
14/03/26 11:46:41 INFO bzip2.Bzip2Factory: Successfully loaded & initialized
native-bzip2 library system-native
14/03/26 11:46:41 INFO zlib.ZlibFactory: Successfully loaded & initialized
native-zlib library
14/03/26 11:46:41 INFO Configuration.deprecation: hadoop.native.lib is
deprecated. Instead, use io.native.lib.available
Native library checking:
hadoop: true

> Key: HADOOP-10359
> URL: https://issues.apache.org/jira/browse/HADOOP-10359
> Project: Hadoop Common
> Issue Type: Improvement
> Components: native
> Affects Versions: 2.2.0
> Environment: Mac OS X 10.8.5
> Oracle JDK 1.7.0_51
> Hadoop 2.2.0-CDH5.0.0-beta-2
> Reporter: Ilya Maykov
> Priority: Minor
> Attachments: HADOOP-10359-native-bzip2-for-os-x.patch
>
>
> While testing the patch for HADOOP-9648, I noticed that the bzip2 native
> compressor/decompressor support wasn't working properly. I dug around a bit
> and got native bzip2 support to work on my macbook. Will attach a patch in a
> bit. (This probably needs to be tested on FreeBSD / Windows / Linux, but I
> don't have the time to set up the necessary VMs to do it. I assume the build
> bot will test Linux).
