[jira] [Created] (FLINK-7955) Rowtime attribute cannot be
aggregated in group window of stream Table API
Fabian Hueske created FLINK-7955:
------------------------------------
Summary: Rowtime attribute cannot be aggregated in group window of stream Table API
Key: FLINK-7955
URL: https://issues.apache.org/jira/browse/FLINK-7955
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.3.2, 1.4.0
Reporter: Fabian Hueske
The following query fails with a {{NullPointerException}}:
{code}
val windowedTable = table
.window(Tumble over 5.milli on 'rowtime as 'w)
.groupBy('w, 'word)
.select('word, 'rowtime.count, 'w.start, 'w.end)
{code}
Equivalent SQL queries or Table API queries that use a processing time attribute are working.
