Description

This was found by Kihwal Lee as part of HDFS-8865 work in this comment.

The unit test testQuotaByStorageTypePersistenceInFsImage/testQuotaByStorageTypePersistenceInFsEdit failed to detect this because they were using an obsolete
FsDirectory instance. Once added the highlighted line below, the issue can be reproed.

++++>fsdir = cluster.getNamesystem().getFSDirectory();
INode testDirNodeAfterNNRestart = fsdir.getINode4Write(testDir.toString());
