------------------------------------
Summary: Drop use of the internal Bzip2TextInputFormat
Key: PIG-4591
URL: https://issues.apache.org/jira/browse/PIG-4591
Project: Pig
Issue Type: Wish
Components: data, tools
Affects Versions: 0.14.0
Environment: set pig.noSplitCombination to false and
pig.maxCombinedSplitSize hight enought so combination nof input files do happen.
Reporter: Remi Catherinot
Priority: Minor
When loading mutiple files which not all the files sharing the same compressor
(load gz + bz2 + rawata files for example), depending on the last file used,
PigStorage will use either Bzip2TextInputFormat if the last file ends with .bz2
end fail, or PigStorage will use TextInputFormat in any other case and succeed
in ready all types of files (including the bz2 one).
A = LOAD 'file1.gz,file2.bz2' USING PigStorage(); <-- this will fail
B = LOAD 'file2.bz2,file1.gz' USING PigStorage(); <-- this will succeed
I think another person suggested in the dev mailing list to drop the use of the
internal pig Bzip2TextInputFormat because hadoop now better handle those cases
(bz2 compression & co). I don't push the patch yet because i don't have a fully
comliant pig test environnement so i'm not able to be sure this won't introduce
a regression with the minimal supported level version of hadoop by pig
0.14/0.15 + i need to know if you agree in drop the internal Bzip2 stuff and
rely on the hadoop implementation.
