[jira] [Commented] (BEAM-1802) Spark Runner does not shutdown
correctly when executing multiple pipelines in sequence
[ https://issues.apache.org/jira/browse/BEAM-1802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15940266#comment-15940266 ]
Amit Sela commented on BEAM-1802:
---------------------------------
[~iemejia] do you stop the pipeline between executions ?
{code}
Pipeline p = ...
p.apply().apply()..
p.waitUntilFinish()
// do you call stop() ?
{code}
