Mr Bsd commented on HADOOP-7657:
--------------------------------
As far as i understand, LZ4 is just a compression algorithm, and does not
define an output format.
The one proposed in the open-source file "LZ4Demo" is just an example, and
obviously made to work with pipe, i.e. unseekable input and output.
> Add support for LZ4 compression
> -------------------------------

> Key: HADOOP-7657
> URL: https://issues.apache.org/jira/browse/HADOOP-7657
> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: Mr Bsd
> Labels: compression
>
> According to several benchmark sites, LZ4 seems to overtake other fast
> compression algorithms, especially in the decompression speed area. The
> interface is also trivial to integrate
> (http://code.google.com/p/lz4/source/browse/trunk/lz4.h) and there is no
> license issue.
