Thanks for the info Anil. I first tried a MR which did Put's, based on the
examples at [1] but this was much too slow, as you said. I switching to
writing HFiles directly via HFileOutputFormat solves the issue.
Also, I wanted to post an issue I ran into, in case anyone runs into it in
the future.
Hi Marcell,
Since key is changing you will need to rewrite the entire table. I think
generating HFlies(rather than doing puts) will be the most efficient here.
IIRC, you will need to use HFileOutputFormat in your MR job.
For locality, i dont think you should worry that much because major
