[jira] [Commented] (SPARK-19690) Join a streaming DataFrame with a batch DataFrame may not work

    [ https://issues.apache.org/jira/browse/SPARK-19690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16136171#comment-16136171 ] 

Jose Torres commented on SPARK-19690:
-------------------------------------

This will be fixed by SPARK-21765; we can restrict the streaming aggregation strategy to only the subtrees of the logical plan which are actually streaming.

> When joining a streaming DataFrame with a batch DataFrame, if the batch DataFrame has an aggregation, it will be converted to a streaming physical aggregation. Then the query will crash.
