Íñigo Goiri commented on HDFS-12802:
------------------------------------
Yetus came back with a warning for failed unit test but the report doesn't show
any.
Chekcing manually, the related test is there and passed as expected:
https://builds.apache.org/job/PreCommit-HDFS-Build/22628/testReport/org.apache.hadoop.hdfs.server.federation.resolver/TestMountTableResolver/
I think this is good to go; [~linyiqun], [~chris.douglas], do you mind taking
hopefully a last check?

> Currently, the {{MountTableResolver}} caches the resolutions for the
> {{PathLocation}}. However, this cache can grow with no limits if there are a
> lot of unique paths. Some of these cached resolutions might not be used at
> all.
> The {{MountTableResolver}} should clean the {{locationCache}} periodically.
