changxue commented on IOTDB-5090: --------------------------------- 是在datanode启动失败的时候会有这个bug。启动失败会走停止流程,但这两个Impl只有在启动成功时才会被初始化,所以加了一个npe判断. 我的重现方法: 1. 将集群的一个节点停止 2. 将单机的data替换这个集群节点的data目录 3. start-datanode.sh 结果没有NPE: !screenshot-1.png|width=617,height=237! > Npe when stop data node > ----------------------- > > Key: IOTDB-5090 > URL: https://issues.apache.org/jira/browse/IOTDB-5090 > Project: Apache IoTDB > Issue Type: Bug > Reporter: Gaofei Cao > Assignee: 伊丹翔 > Priority: Minor > Labels: pull-request-available > Attachments: image-2022-11-30-16-13-02-229.png, screenshot-1.png > > > !image-2022-11-30-16-13-02-229.png|width=617,height=237! -- This message was sent by Atlassian Jira (v8.20.10#820010)
