[jira] [Commented] (IOTDB-5231) [monitor]datanode could not start when binding 9091 error
[ https://issues.apache.org/jira/browse/IOTDB-5231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17653801#comment-17653801 ]
changxue commented on IOTDB-5231:
---------------------------------
The log level should be warning, rather than error.

> [monitor]datanode could not start when binding 9091 error
> environment:
> 3C3D cluster, rel/1.0 branch
> 1. enable prometheus monitor
> 2. the prometheus service has not been started
> problem:
> 1. 监控是附加功能，打开它并且它工作不正常（可以warning），但不应该出现error，不应该影响rpc service等的启动。
> 2. 这种情况下，stop-datanode.sh 是不能成功停止成功的，需要kill
> 3. confignode启动成功，且成功绑定了9091, datanode再绑定9091，结果失败。需要使之成功。
