Hi Alvin,

  I did a simple test under the flink master branch and it works. And I have checked the `primaryKey` implementation:
public Builder primaryKey(String... columnNames) {
Preconditions.checkNotNull(columnNames, "Primary key column names must not be null.");
return primaryKey(Arrays.asList(columnNames));
}
  I think it won't cause problem. Can you share more information, such as the context of your code?
