Subject [jira] [Commented] (ATLAS-297) KafkaNotificationTest.testSendReceiveMessage fails when atlas-server is running on the same machine
Date Fri, 13 Nov 2015 10:33:10 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15003832#comment-15003832
] 

Hemanth Yamijala commented on ATLAS-297:
----------------------------------------

I debugged the issue of the failing integration tests today, and wanted to give a quick update..

The issue seems to be that the mode in which the tests run is that the web server is started
as part of the maven pre-integration-test phase (start-jetty). The KafkaNotification class
which is initialized as part of this phase brings up the Zookeeper & Kafka servers on
random ports, with ephemeral configuration enabled. But the test runs with a different instance
of the KafkaNotification class which needs to *connect* and not bind. Hence, it needs knowledge
of the actual ports, which it doesn't have - hence the failure.

Will think up some solution for this.
