Hi, I have a table, which has close to a billion rows.. I am trying to create an index for the table, when I do the alter command, I always end up with map-reduce jobs with errors. The same runs fine for small tables though, I also notice that the number of reducers are set to 24, even if set manually to 1 and also the reduce percentage changes in a bizarre way, it increases, then decreases and finally reaches 100 with a message job ended with errors. It would be useful, if I can get help on this..
Thanks, Siddharth
