Subject [jira] Updated: (HADOOP-2664) lzop-compatible CompresionCodec
Date Wed, 13 Feb 2008 23:29:08 GMT

Chris Douglas updated HADOOP-2664:
----------------------------------

    Status: Open  (was: Patch Available)

-1

I'm pulling this back. The writes from the cstr and its (related) silent incompatibility with
SequenceFile are sufficient to prevent it from being checked in. It reads and writes lzop-compatible
files, but it is inadequate as a general compression codec. SequenceFile explicitly checks
for a non-native version of GzipCodec, but surely there's a better way to effect this.

That said, it should be noted that one can still write ".lzo" files from LzoCodec that aren't.
The incompatible change in this patch- that asserts precedence for the .lzo extension and
changes the former to .lzo_deflate - should be considered for 0.17 regardless of what happens
with this patch.
