Yukun Zhou commented on IOTDB-5600:
-----------------------------------
Such problem cannot be fixed in current cluster architecture, but can be
avoided by ensuring plenty memory resource for schema module.
> Metadata between nodes is inconsistent

> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: 刘珍
> Assignee: Yukun Zhou
> Priority: Major

> master_0228_3ef36de
> { drop database + create metadata , insert 1 point/sensor } , execute 10
> times in serial .
> benchmark execution complete，cli -e "flush"
> Metadata between nodes is inconsistent.

> 测试流程：
> 1.启动3副本3C5D . 把自动创建元数据设置为false
> ConfigNode
> MAX_HEAP_SIZE="20G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> DataNode
> MAX_HEAP_SIZE="20G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> COMMON：
> schema_replication_factor=3
> data_replication_factor=3
> enable_auto_create_schema=false
> 3ConfigNode ：
> 172.16.2.23
> 172.16.2.24
> 172.16.2.25
> 5DataNode：
> 172.16.2.2
> 172.16.2.3
> 172.16.2.4
> 172.16.2.5
> 172.16.2.6
> 2. 运行如下脚本（172.16.2.26机器，/data/iotdb/benchmark_v1下）：
> for i in {1..10}
> do
> /data/iotdb/m_0227_2bc29bb/sbin/start-cli.sh -h 172.16.2.2 -e "drop
> database root.test.*;"
> sh ./iotdb.sh 5516 > 5516_$i.out
> done
> 运行完成，cli 执行flush。
> 3. 验证各节点元数据与数据一致性
> 所有节点在线：count devices
> down掉ip2：count devices
> down 掉ip6：count devices
> 查询结果不一致。
