> Key: HDDS-1291
> URL: https://issues.apache.org/jira/browse/HDDS-1291
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Xiaoyu Yao
> Assignee: Xiaoyu Yao
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 0.4.0
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> After HDDS-1138, the OM client will not talk to SCM directly to fetch the
> pipeline info. Instead the pipeline info is returned as part of the
> keyLocation cached by OM.
>
> In case SCM pipeline is changed such as closed, the client may get invalid
> pipeline exception. In this case, the client need to getKeyLocation with
> OmKeyArgs#refreshPipeline = true to force OM update its pipeline cache for
> this key.
>
> An optimization could be queue a background task to update all the
> keyLocations that is affected when OM does a refreshPipeline. (This part can
> be done in 0.5)
> {code:java}
> oldpipeline->newpipeline{code}
