SOLR-13924: AwaitsFix: MoveReplicaHDFSTest
I've AwaitsFix'ed the entire class due to this bug so it no longer triggers
jenkins failures, but I should point out that some of the individual test
methods have already been BadApple'ed with an annotation pointing at
SOLR-12028, however:
* the SOLR-12028 BadApple annotations were added ~2018-10
* Prior to SOLR-13843 / SOLR-13924 failures, the last jenkins failure from
this class was 2019-03-13
** [~krisden] did a lot of general HDFS test improvements, including
modifications to this class, in SOLR-13330 ~2019-03 which where probably
related to the drop off in failures
* So once SOLR-13924 is fixed, the entire test should be re-evaluated to
confirm if all the SOLR-12028 annotations can be removed.

> Key: SOLR-13924
> URL: https://issues.apache.org/jira/browse/SOLR-13924
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 8.3
> Reporter: Chris M. Hostetter
> Assignee: Shalin Shekhar Mangar
> Priority: Major
>
> 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
