Ted Dunning commented on PIG-389:
---------------------------------
Here is the script
log = LOAD 'tutorial/data/excite-small.log' USING PigStorage('\t') as (ip,
date, query);
t1 = GROUP log by ip;
describe t1;
counts = FOREACH t1 {
cnt = COUNT(log);
GENERATE group as ip, cnt as cnt;
}
describe counts;
r = FILTER counts by -cnt > 2;
describe r;
dump r;
> Unary minus not supported in FILTER expressions
