刘珍 commented on IOTDB-5516:
---------------------------

复现流程：
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

运行如下脚本， 能复现。
for i in {1..10}
do
        /data/mpp_test/m_0214_eaee1d8/sbin/start-cli.sh -h 192.168.10.74 -e 
"drop database root.test.*;"
        sh ./iotdb.sh 5516 > 5516_$i.out
done

{color:red}*drop database 操作不应该是异步的。*{color}
