Michi Mutsuzaki updated ZOOKEEPER-1840:
---------------------------------------
Assignee: Alexander Shraer
> Server tries to connect to itself during dynamic reconfig
> ---------------------------------------------------------
>
> Key: ZOOKEEPER-1840
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1840
> Project: ZooKeeper
> Issue Type: Bug
> Components: quorum
> Affects Versions: 3.5.0
> Reporter: Bruno Freudensprung
> Assignee: Alexander Shraer
> Priority: Minor
>
> Submitted this bug on a suggestion of Alexander Shraer (see
> https://issues.apache.org/jira/browse/ZOOKEEPER-1691)
> How to reproduce:
> == Server 1 zoo.cfg:
> standaloneEnabled=false
> dynamicConfigFile=<path to>/confdyn1/zoo.cfg.dynamic
> == Server 1 zoo.cfg.dynamic:
> server.1=localhost:2888:3888:participant;localhost:2181
> == Server 2 zoo.cfg:
> standaloneEnabled=false
> dynamicConfigFile=<path to>/confdyn2/zoo.cfg.dynamic
> == Server 2 zoo.cfg.dynamic (it is "aware" of the server 1, as mentioned in
> the Dynamic Reconfiguration - User Manual
> that I should have read more carefully yesterday):
> server.1=localhost:2888:3888:participant;localhost:2181
> server.2=localhost:2889:3889:participant;localhost:2182
> Start server 1
> Start server 2
> == use client 1 to issue a reconfig command on server 1:
> [zk: localhost:2181(CONNECTED) 1] reconfig -add
> server.2=localhost:2889:3889:participant;localhost:2182
> Committed new configuration:
> server.1=localhost:2888:3888:participant;localhost:2181
> server.2=localhost:2889:3889:participant;localhost:2182
> version=100000003
> There are strange stack traces in both server consoles.
