Cristian Galán updated PIG-4906:
--------------------------------
Release Note:
-4 new functions: SUM, AVG, MAX and MIN for BigDecimal and 4 test for each
function.
-An another outputschema. This output takes the inner alias and type of
inputschema and returns the same alias with "_over" and the type. This is
because in a foreach like the next:
x = FOREACH SUM {
ini = FOREACH test GENERATE id, id_2;
GENERATE FLATTEN(MYSTITCH(ini, MYOVER(test.impt_prima, 'sum(bigdecimal)'),
MYOVER(test.impt_1, 'sum(bigdecimal)'),
MYOVER(test.impt_2, 'sum(bigdecimal)')));
with the normal OVER function the foreach fails because all MYOVERS return the
same alias.
Status: Patch Available (was: Open)
> Add Bigdecimal functions in Over function
