-------------------------------------
Summary: java.lang.ArrayStoreException with for-loop inside UDF
Key: SYSTEMML-1822
URL: https://issues.apache.org/jira/browse/SYSTEMML-1822
Project: SystemML
Issue Type: Bug
Reporter: Gus Jenkins
Hey I'm working on something and came upon a bug. I boiled the problem down to
the following. If I run the following code, it works fine. But if I run the
latter code with a simple for-loop in the UDF, I get an error. Please see
below. I also included the error message.
{code}
discrete_samples = function(matrix[double] weights) return(double ix){
ix = 0.00
}
weights = matrix(1, rows = 5, cols = 1)
ix = discrete_samples(weights)
print("Index here: " + ix)
{code}
{code}
discrete_samples = function(matrix[double] weights) return(double ix){
ix = 0.00
for(j in 1:5){
print("Hello")
}
}
weights = matrix(1, rows = 5, cols = 1)
ix = discrete_samples(weights)
print("Index here: " + ix)
{code}
