I use the following example to set my own delimiter, I hope it's easy to adjust for your own needs:
hive> create external table input (a int, b string, c float) row format delimited fields terminated by "\t" stored as sequencefile location 's3://path/to/data/input/'; hive> create external table output (a int, b string, c float) row format delimited fields terminated by "~" stored as textfile location 's3://path/to/data/output/'; hive> insert overwrite table output select * from input; Let me know if it works!

I have 200+ columns so it is quite an ugly thing. No shortcut?

Instead of doing a "SELECT * ", you may like to use concat function to have a separator of your choice.
