Description

Based on recent jenkins test failures, it appears that attemping to use the "MoveReplica" command on HDFS has a high chance of failure due to an underlying NPE.

I'm not sure if this bug only affects HDFS, or if it's just more likly to occur when using HDFS due to some timing quirks.

It's also possible that the bug impacts non-HDFS users just as much as HDFS users, but only manifests in our tests due to some quick of our cloud-hdfs test configs.

The problem appears to be new in 8.3 as a result of changes made in SOLR-13843
