Hong Tang commented on HADOOP-6837:
-----------------------------------

@nicolas, per our offline conversation last week, have you looked into whether 
the licensing of liblzma is suitable for inclusion in Hadoop? Liblzma seems 
better in the sense that its API resembles closely the APIs of other 
compression libraries like bzip or zlib and should shrink the amount of coding 
work needed to support C (and Java over JNI).

> generally achieves higher compression ratios than both gzip and bzip2.
