Yes Manish, Zip is not supported in hadoop. You may have to use gzip
instead.Regards

Thanks Bejoy. I have zip file there is sense to convert into gzip again.
Chuck, I got what you are trying to say. So I need to process it outside HDFS
and bring the text file into HDFS.

Hi Manish
Gzip works well if you have the compression codec available in
'io.compression.codes' . Gzip codec is present in default.
I don't think untar ing world be done by map reduce jobs. So tar files may
not work with hive, you need to untar the files out of hadoop hive as a
prerequisite.

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

I have seen that error when I try to overwrite an existing file.
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.

Manish the table that has been created for zipped text files should be
defined as sequence file, for example
CREATE TABLE my_table_zip(col1 STRING,col2 STRING) ROW FORMAT DELIMITED
FIELDS TERMINATED BY ',' stored as sequencefile;
After this you can use regular load command to load these files, for
example
load data local inpath 'path-to-csv-file.gz' into table my_table_zip;
hope this helps

Hi Richin,
Thanks! Yes this is what I wanted to understand how to load zip file to
Hive table. Now, I'll try this option.

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: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.

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’;
OR
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.

Hivers,
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?
