Description
There has an 'NullPointException' when use RANK() and DENSE_RANK() in over window.
@Test
def testDenseRankOnOver(): Unit = {
val t = failingDataSource(TestData.tupleData5)
.toTable(tEnv, 'a, 'b, 'c, 'd, 'e, 'proctime.proctime)
tEnv.registerTable("MyTable", t)
val sqlQuery = "SELECT a, DENSE_RANK() OVER (PARTITION BY a ORDER BY proctime) FROM MyTable"
val sink = new TestingAppendSink
tEnv.sqlQuery(sqlQuery).toAppendStream[Row].addSink(sink)
env.execute()
}
