Subject Storing data into hive table having columns from multiple files
Date Thu, 20 Jun 2013 09:21:11 GMT
Hi All,

I have a query on a scenario which is below:

There are 2 files "file1", "file2". And a hive table "test" which is created with 15 columns
with "," delimiter.
"file1" contains 25 columns and "file2" contains 15 columns having seperator as ",":
 
But, out of 25 columns, 10 columns of data from file1 are inserted to hive table "test"
and out of 15 columns, 5 columns of data from file2 are inserted to the same hive table "test"
(lets forget about the remaining 15 columns from file1 and 10 columns from file2)
 
First, "file1" is processed and then "file2" is processed.
When "file1" is processed, 10 columns gets inserted into "test" table for a row.
When "file2" is processed, 5 columns have to be inserted into "test" table of the same row.
 
Could you please help me on how to insert the 5 columns of file2 to the same row in "test"
table?
(which has 10 columns of data inserted from file1 for that row)


Thanks & Regards,
Varaprasada Reddy
