Hong Tang updated HADOOP-3315:
------------------------------
Fix Version/s: 0.18.3
0.20.0
Release Note:
Main changes of this patch since last upload:
* Solving the missing LzoCodec issue.
* Enhanced the unit tests.
was:TFile patch
Status: Patch Available (was: In Progress)
The patch is tested to work with trunk head, 0.18.3 and 0.20.
For 0.18.3 and 0.20, it works as my previous upload and would use the built-in
LzoCodec for "lzo" compression.
For trunk, by default, "lzo" compression is not support. User must specific the
class name for a 3rd-party lzo compression library through property
"io.compression.codec.lzo.class", and set the classpath and java.library.path
properly. The code is tested to work with hadoop-gpl-compression:
http://code.google.com/p/hadoop-gpl-compression/.
