What about .gz OR tar file. Does this unzip require at HDFS and load into hive? How you resolve it.

But, more importantly, Hive cannot understand ZIP files. There was a long thread about this just a few days ago. Your table def says "stored as textfile" but you are not giving it a text file.

I thought his question was how to use zip files or any compressed files in Hive tables. Yeah, seems like you can’t do that see:http://mail-archives.apache.org/mod_mbox/hive-user/201203.mbox/%3CCAENxBwxkF--3PzCkpz1HX21=gb9yvasr2jl0u3yul2tfgu0...@mail.gmail.com%3E But you can always compress your files in gzip format and they should be good to go.

How could this possibly work with a zip/tar file that can contain ASCII 10 characters at random locations, and certainly does not have ASCII 10 at the end of each data record?

Hive uses newline as the record separator. A ZIP file will certainly newline characters. So I doubt this is possible. BUT, I would like to hear from anyone who has solved the "newline is always a record separator" problem, because we ran into it for another type of compressed file.

All the files has similar schema (structure). Say 50 *.txt files are zipped into a single zip file can we load data directly from this zip file OR should we need to unzip first?
