Yes, I've registered the piggybank jar in the pig script - see script
a = load '/some_dir/some_aggregation/_logs/history' using
HadoopJobHistoryLoader() as (j:map, m:map,
b = foreach a generate j#'PIG_SCRIPT_ID' as id, j#'USER' as user,
j#'JOBNAME' as script_name,
(Long) j#'SUBMIT_TIME' as start, (Long) j#'FINISH_TIME' as end;
c = group b by (id, user, script_name)
d = foreach c generate group.user, group.script_name, (MAX(b.end) -
I've also downloaded the PIG from cloudera version 4.0.1 again and greped
the piggybank.jar for the "HadoopJobHistoryLoader" class - but I'm still
not founding the class?!
Greped also /usr/lib/pig/contrib/piggybank/java/piggybank.jar - same
What I'm doing wrong here?
Thanks for any help!
