A noop patch has these failures:
```
org.apache.hadoop.hdfs.TestDFSUpgradeFromImage.testUpgradeFromRel1BBWImage
org.apache.hadoop.hdfs.TestDecommissionWithStripedBackoffMonitor.testDecommissionWithMissingBlock
org.apache.hadoop.hdfs.server.datanode.TestDataNodeRollingUpgrade.testWithLayoutChangeAndFinalize
```
A push with the backport has these failures:
```
org.apache.hadoop.hdfs.server.blockmanagement.TestUnderReplicatedBlocks.testSetRepIncWithUnderReplicatedBlocks
org.apache.hadoop.hdfs.server.datanode.TestDataNodeRollingUpgrade.testWithLayoutChangeAndRollback
```
One overlap: TestDataNodeRollingUpgrade. Other seems unrelated. Let me try a
repush.

> We have HBase RegionServer and Hdfs DataNode running in one pod. When the pod
> restarts, we found that data locality is lost after we do a major compaction
> of hbase regions. After some debugging, we found that upon pod restarts, its
> ip changes. In DatanodeManager, maps like networktopology are updated with
> the new info. host2DatanodeMap is not updated accordingly. When hdfs client
> with the new ip tries to find a local DataNode, it fails.
