That can lead to "file not found" errors on the sta= te store delta files as the micro-batch-with-no-shuffle will not run certai= n tasks and therefore not generate the expected state store delta files. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
