Kai Zheng commented on HADOOP-12662:
------------------------------------

Thanks [~cmccabe] for the review and nice comments!

bq. It seems like this should be named bundle_native_lib or something like 
that, rather than check_bundle_lib
Sounds much clearer to use {{bundle_native_lib}} as the checking is just the 
essential part of it.

bq. the 'X' construction isn't needed in bash. Suggest using this instead
Ah, see. Thanks for the reminding and sample codes. I just got what [~aw] meant.

bq. try using this instead (note the double equals sign)
Sure. Glad I can be refreshed in my shell aspect.

Will update the patch accordingly.

> Per some discussion with [~cmccabe], it would be good to refine and make it 
> consistent the behaviors in bundling native libraries when building dist 
> package.
> For all native libraries to bundle, if the bundling option like 
> {{-Dbundle.snappy}} is specified, then the lib option like {{-Dsnappy.lib}} 
> will be checked and ensured to be there, but if not, it will then report 
> error and fail the building explicitly.
> {{BUILDING.txt}} would also be updated to explicitly state this behavior.
