apache pig - Hadoop Load and Store -


when trying run pig script has 2 "store" same file way

store alert_message_count 'out'; store warning_message_count 'out';

it hangs, mean not proceed after showing 50% done.

is wrong? cant store both results in same file(folder)?

normally hadoop mapreduce won't allow save job output folder exists, guess isn't possible either (seeing pig translates commands series of m/r steps) - expect form of error message rather hang.

if open cluster job tracker, , @ logs task, log yield of note can diagnose further?

might worth checking pig mailing lists (if haven't already)

if want append 1 dataset another, use union keyword:

grunt> all_count = union alert_message_count, warning_message_count; grunt> store all_count 'out';
