Instead of using String for join type, always use the link here.
If there are typos on the join type, using the link in client code will cause
compile time failure, which using string itself will cause run-time failure.
Spark(as of 1.4)'s join type is a String. Could use enum or case objects here,
but there are clients using the String api, so will push that change till later.
