-----------------------
> The log dispatcher is inconsistent with the search index of the wal node
> ------------------------------------------------------------------------

> Affects Versions: 0.14.0-SNAPSHOT
> Reporter: 刘珍
> Assignee: 张洪胤
> Priority: Major
> Fix For: 1.0.0
>
> Attachments: ip74_logs.tar.gz, more_metadata.conf, screenshot-1.png

> 问题描述
> {color:#DE350B}*log dispatcher与wal node的search index不一致 ，
> datanode重启成功后日志一直刷*{color}：

> MultiLeaderConsensus，3副本3节点
> 1. 创建元数据过程中，kill ip74 的datanode PID
> benchmark配置文件见附件。
> 2. 清空ip74 的操作系统缓存，启动ip74的datanode
> 3. 再次重新运行benchmark同一配置，IS_DELETE_DATA=true
> 这个参数为true，会先执行delete storage group root.test.*;
> benchmark运行完成，stop ip74的datanode服务
> 备份data 为/data/mpp_test/m_0908_7915b3f/datanode/data_for_recovery_Test
> 4. 清ip74操作系统缓存，启动datanode服务
> 再次运行benchmark同一配置，benchmark运行完成，
> 查看ip74的日志，看到
