----------------------------------
Summary: Fix UDTF codegen bug when window follow by join( UDTF)
Key: FLINK-6736
URL: https://issues.apache.org/jira/browse/FLINK-6736
Project: Flink
Issue Type: Sub-task
Components: Table API & SQL
Affects Versions: 1.3.0
Reporter: sunjincheng
Assignee: sunjincheng
When we run the tableAPI as follows:
{code}
val table = stream.toTable(tEnv, 'long.rowtime, 'int, 'double, 'float, 'bigdec,
'date,'pojo, 'string)
val windowedTable = table
.join(udtf2('string) as ('a, 'b))
.window(Slide over 5.milli every 2.milli on 'long as 'w)
.groupBy('w)
.select('int.count, agg1('pojo, 'bigdec, 'date, 'int), 'w.start, 'w.end)
{code}
We will get the error message:
{code}

{code}
The reason is {{val generator = new CodeGenerator(config, false,
inputSchema.physicalTypeInfo)}} `physicalTypeInfo` will remove the
TimeIndicator.
I think we should fix this. What do you think [~fhueske] [~twalthr] , And hope
your suggestions. :)
