Vinod Kumar Vavilapalli updated HADOOP-7206:
--------------------------------------------
Attachment: HADOOP-7206-20120302.txt
bq. snappy.lib variable is hardcoded to /usr/lib which may not be true in the
case of 64 bit lib where snappy is in /usr/lib64.
Thanks for pointing this out, Giri. I just removed using explicit ends for
compiling snappy. I guess we need this for trunk too, but we can do it later.
Attaching patch, that should fix this.

> Snappy is a compression/decompression library. It does not aim for maximum
> compression, or compatibility with any other compression library; instead, it
> aims for very high speeds and reasonable compression. For instance, compared
> to the fastest mode of zlib, Snappy is an order of magnitude faster for most
> inputs, but the resulting compressed files are anywhere from 20% to 100%
> bigger. On a single core of a Core i7 processor in 64-bit mode, Snappy
> compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec
> or more.
