[jira] [Updated] (DRILL-2550) Drillbit disconnect from ZK results
in drillbit being lost until restart
[ https://issues.apache.org/jira/browse/DRILL-2550?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chris Westin updated DRILL-2550:
--------------------------------
Affects Version/s: 0.8.0
> Drillbit disconnect from ZK results in drillbit being lost until restart
> ------------------------------------------------------------------------
>
> Key: DRILL-2550
> URL: https://issues.apache.org/jira/browse/DRILL-2550
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Flow
> Affects Versions: 0.8.0
> Reporter: Ramana Inukonda Nagaraj
> Assignee: Chris Westin
> Priority: Minor
> Fix For: 0.9.0
>
>
> Not quite sure if this is an issue or even if its important- maybe someone can think of a situation where this might be a bigger issue.
> Steps taken to recreate:
> 1. Startup drillbits on multiple nodes. (They all come up and form a 8 node cluster)
> 2. Start executing a long running query.
> 3. Use TCPKILL to kill all connections between one node and zookeeper port 5181.
> Drill seems to behave very gracefully here - I see a nice error message saying Query failed: ForemanException: One more more nodes lost connectivity during query. Identified node was atsqa6c61.qa.lab
> However, once I start allowing connections back the node is not brought back as part of the cluster until a drillbit restart.
