Hi all, I realize I'm using an older version of slider, but I think this was the last release to be compiled against Hadoop 2.4 with Kerberos working. We aren't positioned to upgrade to 2.6 yet. That being said, Slider has worked pretty flawlessly for us so far.
I checked JIRA, and didn't find a bug report matching this scenario. I recently decommissioned several of our NodeManagers. The NodeManagers are in decommissioned status in the RM UI. However, Slider continues to request those nodes (based on historical preference I assume). 15/01/30 17:01:26 INFO state.RoleHistory: There're 1 nodes to consider for STORM_UI_SERVER 15/01/30 17:01:26 INFO state.OutstandingRequest: Submitting request for container on [NODE A - FQDN censored] NODE A in this case has been decommissioned and shows up in the RM UI as decommissioned as well as in the yarn.exclude list. If this is fixed in a later version, then I'm okay with that. I figured it was worth mentioning though. More to the point, is there a way to clear role history (or even modify it by hand) and force requests to go somewhere else? Thanks, Tim
