Please add timestamps to pig map/reduce progress messages
---------------------------------------------------------
Key: PIG-12
URL: https://issues.apache.org/jira/browse/PIG-12
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich
Priority: Minor
>From one of the users:
------------------------------
I'm spending a lot of time trying to optimize my pig queries for short
run-times. This process would be much easier if, in the progress output
from pig (currently on stdout, but hopefully soon moving to
stderr?!), the
initiation and completion of each map/reduce job could be
timestamped. Pig
already spits out messages of the form "----- MapReduce Job -----",
"Input:
...", "Combine: ...", etc; could you just add a "Timestamp: ..."
field as well? Or ideally, both "Starting timestamp: ..." and
"Finishing
timestamp ...".
Additional comments from another user:
------------------------------------------------------
I'm adding my vote for this as well.
I'd like to know timestamp and "running time" in seconds or D;H:M:S:
Thu Oct 25 10:06:01 GMT 2007 (0:00:12:56): 56% done
Starting and stopping timestamps in the log would also be valuable.
Unforutately, there's no "workaround" such as putting a date command before and
after the pig command in logging --
queuing times can be seconds to hours and completely mess up any notion of job
execution time.
