David Ciemiewicz updated HADOOP-6335:
-------------------------------------
Summary: Support reading of concatenated gzip and bzip2 files (was:
Support reading of concatenated gzip files)
bzip2 also supports concatenation of individually compressed files.
bzcat has absolutely no problem reading all of the data in a single
concatenated file.
Unfortuantely, M/R loses records. My Hadoop Streaming and Pig jobs saw only 2%
of the data in the concatenated file. That's a 98% data loss. Not very good.
There should be no data loss in reading these concatenated files.
