Subject Re: Converting from textfile to sequencefile using Hive
Date Mon, 30 Sep 2013 18:54:56 GMT
Hi Nitin,

No offense taken. Thank you for your response. Part of this is also trying
to find the right tool for the job.

I am doing queries to determine the cuts of tweets that I want, then doing
some modest normalization (through a python script) and then I want to
create sequenceFiles from that.

So far Hive seems to be the most convenient way to do this. But I can take
a look at PIG too. It looked like the "STORED AS SEQUENCEFILE" gets me 99%
way there. So I was wondering if there was a way to get those ids in there
as well. The last piece is always the stumbler :)

Thanks again,
