ASF GitHub Bot commented on METRON-1695: ---------------------------------------- Github user anandsubbu commented on the issue: https://github.com/apache/metron/pull/1207 Thanks much @nickwallen for giving it another spin! Hey @MohanDV , let me know if my below explanation makes sense. @nickwallen , would you have any thoughts on this? > @MohanDV , as a part of my commit, I have moved all the UI related elements from REST to the PCAP config tab. > > In my understanding, the following parameters are not directly related to the PCAP core service, but are functionally related to REST (used by the PCAP query panel UI): > > * pdml.script.path > * base.path > * base.interim.result.path > * final.output.path > * page.size > * yarn.queue > * finalizer.threadpool.size > > For this reason, I did not move these properties out of the rest_application.yml. > > > @MohanDV Changing a REST Setting triggers Ambari to Restart PCAP Topology > > With my current changes, modifying any config setting in the PCAP tab will require restarting both Metron PCAP and Metron REST services--which is necessary since user can change a PCAP-service related property or a PCAP-REST related property (or both). The converse, which you noted, i.e. changing any REST config does not require restarting the PCAP topology. Here's a screenshot after making changes to REST config... > > ![image](https://user-images.githubusercontent.com/20395490/46430735-8e6f0700-c767-11e8-8308-728771635480.png) > Expose pcap properties through Ambari > ------------------------------------- > > Key: METRON-1695 > URL: https://issues.apache.org/jira/browse/METRON-1695 > Project: Metron > Issue Type: Bug > Reporter: Anand Subramanian > Assignee: Anand Subramanian > Priority: Major > > Currently, the $METRON_HOME/config/pcap.properties file is hardcoded with the > defaults. One has to hand edit the file before deploying the PCAP topology. > These properties should be configurable via Ambari. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
