This patch refines the current union operation to an internal LOP operation. Currently, two subsequent operations -- rbind() and unique(), are used to perform the union operation. We rewrite the operation with an internal LOP that uses a HashSet to compute the unique entries and returns them in a matrix. This improves the efficiency of the operation, as it avoids unique(). The order of the input entries is preserved in the output. -- This is an automated message from the Apache Git Service.
