Greg Roelofs commented on HADOOP-6835:
--------------------------------------

OK, so auto-patch doesn't know about the split projects, and hadoop-mapreduce 
patches don't work in hadoop-common.

I tried moving the test case to 
hadoop-common/src/test/core/org/apache/hadoop/io/compress, but it depends on 
too many MR classes to be workable (JobConf, Reporter, RecordReader, FileSplit, 
InputSplit, FileInputFormat, TextInputFormat).  So I guess the procedure is (1) 
reupload the hadoop-common patch and mark as patch-available [actually, I 
missed a fix in TestCodec, so I need to upload a new one anyway]; (2) get that 
past QA and checked in; (3) open a separate MR JIRA, attach the test case, and 
mark it patch-available; and (4) get _that_ past QA and checked in, too.

If there's an easier way, feel free to enlighten me.  (On a related note, I was 
told by Reliable Sources to blame Owen, but he just left town.  Coincidence?)

> When running MapReduce with concatenated gzip files as input only the first 
> part is read, which is confusing, to say the least. Concatenated gzip is 
> described in http://www.gnu.org/software/gzip/manual/gzip.html#Advanced-usage 
> and in http://www.ietf.org/rfc/rfc1952.txt. (See original report at
