Dmitriy V. Ryaboy commented on PIG-1563:
----------------------------------------
+1
question/comment -- any reason you discarded the new buildSimpleFuncSpec I
wrote in the first iteration of this patch? I think it simplifies the code:
{code}
funcList.add(Utils.buildSimpleFuncSpec(
this.getClass().getName(), DataType.CHARARRAY, DataType.CHARARRAY));
{code}
vs
{code}
Schema s = new Schema();
s.add(new Schema.FieldSchema(null, DataType.CHARARRAY));
s.add(new Schema.FieldSchema(null, DataType.CHARARRAY));
funcList.add(new FuncSpec(this.getClass().getName(), s));
{code}
> SUBSTRING function is broken
