PipelineStateMap#removePipeline
add the following code
List<Pipeline> list = query2OpenPipelines.get(new PipelineQuery(pipeline));
if (list != null) {
if (list.remove(pipeline)) {
LOG.warn("Remove a pipeline {} in query2OpenPipelines.", pipeline);
}

> Key: HDDS-3669
> URL: https://issues.apache.org/jira/browse/HDDS-3669
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: SCM
> Affects Versions: 0.6.0
> Reporter: maobaolong
> Assignee: maobaolong
> Priority: Major
>
> The following step can reproduce this issue
> - A new ozone cluster with only a factor three pipeline
> - put a big file(1G) into cluster, during the put process, we kill the
> leader datanode of this pipeline.
> The put command will hang, the following log will fill the scm log file.
