[jira] [Comment Edited] (METRON-1093) Start/stop/restart topologies
use Storm CLI
[ https://issues.apache.org/jira/browse/METRON-1093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16149019#comment-16149019 ]

--------------------------------------------------------------------
Due to this issue, some of the storm topologies end up running post-kerberos. Because of this, some of the topologies would throw authentication errors, since they are stale and haven't been killed/redeployed. Indices might not be generated if the indexing topology were not restarted for e.g.
Another side effect also seen is that Management UI reports the status of the sensors incorrectly. The sensors would show up as stopped, while the actual status is running.

Due to this issue, some of the storm topologies end up as still running post-kerberos. Because of this, some of the topologies would throw authentication errors, since they are stale and haven't been killed/redeployed.
Another side effect also seen is that Management UI reports the status of the sensors incorrectly. The sensors would show up as stopped, while the actual status is running.

> Currently both Ambari status check and Ambari Start/Stop/Restart topologies use Storm REST to get the status of the topologies. This can lead to an inaccurate status when the topologies are running and the Storm UI is not. During an Ambari restart, the topologies wouldn't be restarted when this occurs.
> Ambari needs status check to be quick, so continue to use Storm REST. Modify start/stop/restart to get the running topologies via the Storm CLI.
