Subject Re: Working on LZOP Files
Date Fri, 26 Sep 2014 03:25:02 GMT
Hi Harsha,

I use LZOP files extensively on my Spark cluster -- see my writeup for how
to do this on this mailing list post:

Maybe we should better document how to use LZO with Spark because it can be
tricky to get the lzo jars, native libraries, and hadoopFile() calls all
set up correctly.
