> Avoid insufficient EC pipelines in the container pipeline cache
> ---------------------------------------------------------------
>
> Key: HDDS-11209
> URL: https://issues.apache.org/jira/browse/HDDS-11209
> Project: Apache Ozone
> Issue Type: Bug
> Components: EC, OM
> Affects Versions: 1.4.0
> Reporter: Hongbing Wang
> Assignee: Hongbing Wang
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.5.0
>
>
> OM cached pipeline may not cache container's all datanode information (for
> example, some DNs may not report in time), which can be problematic for EC
> files. If the nodes num is less than the EC data-blocks num, an error will
> occur when reading data:
> {code:java}
> There are insufficient datanodes to read the EC block {code}
> This err will persist until the cache expires (after 6 hours) even if all DNs
> corresponding to the EC file are completely normal.
> So, we should not cache EC pipelines with incomplete data-nodes.
