Dear all,

About splitting support for bzip2, I checked on the JIRA list and found
HADOOP-7386 marked as "Won't fix"; I also found some work done in
branch-0.21(also in trunk), say HADOOP-4012 and MAPREDUCE-830, but not
integrated/migrated into branch-1, so I guess we don't support contatenated
bzip2 in branch-1, correct? If so, is there any special reason? Many thanks!

Hi Yu Li,

The JIRA HADOOP-7823 backported support for splitting Bzip2 files plus
MR support for it, into branch-1, and it is already available in the
1.1.x releases out currently.

Concatenated Bzip2 files, i.e., HADOOP-7386, is not implemented yet
(AFAIK), but Chris over HADOOP-6335 suggests that HADOOP-4012 may have
fixed it - so can you try and report back?

Hi Harsh,

Thanks a lot for the information!

My fault not looking into HADOOP-4012 carefully, will try and veriry
whether HADOOP-7823 has resolved the issue on both write and read side, and
report back.

Hi Hash,

Sorry for the a little late response, busy doing some other work these
days. I have pasted my test steps and result onto HADOOP-7386, and if the
way of my testing is correct, I think concatenated BZip2 file support is
implemented and already in branch-1. I also did some sanity testing and
confirmed splitting BZip2 support also in branch-1. Please let me know if
any comments, thanks.
