-Losing ordering after using ORDER BY
James Newhaven 2012-05-29, 19:25
I've noticed that I seem to be losing the ordering of my relation after
passing the result of an ORDER BY to an EVAL function.
D = FOREACH C GENERATE COUNT($1) as countd;
E = ORDER D BY $0 DESC;
D1 = GROUP E ALL;
D2 = FOREACH D1 GENERATE MyCustomEvalFunc($1);
When inspecting the results in MyCustomEvalFunc I noticed the ordering of
my results isn't the same as relation E (which uses ORDER BY DESC).
Any help appreciated!
