You are right Chuck. 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:
But you can always compress your files in gzip format and they should be good to go.

But TEXTFILE in Hive always has newline as the record delimiter. 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?

Hi Manish,

If you have your zip file at location -  /home/manish/zipfile, you can just point your external
table to that location like
CREATE EXTERNAL TABLE manish_test (field1 string, field2 string) ROW FORMAT DELIMITED FIELDS
TERMINATED BY <your_column_delimiter> STORED AS TEXTFILE LOCATION '/home/manish/zipfile';


If you already have external table pointing to a certain location you can load this zip file
into your table as
LOAD DATA INPATH '/home/manish/zipfile' INTO TABLE manish_test;

Hope this helps.

Another solution would be

Using shell script do following

1.       unzip txt files,

2.       one by one merge those 50 (or N number of) text files into one text file,

3.       then the zip/tar that bigger text file,

4.       then that big zip/tar file can be uploaded into hive.

This could be a problem. 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.

I want to understand that would it be possible to utilize zip/tar files directly into Hive.
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?
