Sandy Ryza created PIG-3160:
-------------------------------
Summary: GFCross uses unnecessary loop
Key: PIG-3160
URL: https://issues.apache.org/jira/browse/PIG-3160
Project: Pig
Issue Type: Improvement
Components: internal-udfs
Affects Versions: 0.10.0
Reporter: Sandy Ryza
The GFCross UDF contains the following code:
{code}
int[] digits = new int[numInputs];
for (int i=0; i<numInputs; i++){
if (i == myNumber){
digits[i] = r.nextInt(numGroupsPerInput);
}else{
digits[i] = 0;
}
}
{code}
As int arrays are initialized with all 0s already, this is equivalent to just
settings digits[myNumber] and leaving the rest alone.
