Answer 1

I know this question is old, but you have a couple of options. You can't control this with FIELDS TERMINATED BY, because that only controls what terminates the fields, not the records. Records in Hive are hard-coded to be terminated by the newline character (even though there is a LINES TERMINATED BY clause, it is not implemented).

1. Write a custom InputFormat that uses a RecordReader that understands non-newline delimited records. Look at the code for LineReader/LineRecordReader and TextInputFormat.
2. Use a format other than text/ASCII, like Parquet. I would recommend this regardless, as text is probably the worst format you can store data in anyway.

Answer 2

try adding the below property in hive-site.xml or you can just try for temporary hive session level.

hive.query.result.fileformat=SequenceFile

Answer 3

By default hive takes in NEWLINE ('\N') as delimiter . You can change the delimiter using:

    ROW FORMAT DELIMITED FIELDS TERMINATED BY ",";
