KevinWikant opened a new pull request #3923:
URL: https://github.com/apache/hadoop/pull/3923
### Description of PR
A rare edge case was noticed in DatanodeAdminDefaultMonitor which causes a DatanodeDescriptor to be added twice to the pendingNodes queue.
- a [datanode is unhealthy so it gets added to "unhealthyDns"](https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/blockmanagement/DatanodeAdminDefaultMonitor.java#L227)
- an exception is thrown which causes [this catch block](https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/blockmanagement/DatanodeAdminDefaultMonitor.java#L271) to execute
- the [datanode is added to "pendingNodes"](https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/blockmanagement/DatanodeAdminDefaultMonitor.java#L276)
- under certain conditions the [datanode can be added again from "unhealthyDns" to "pendingNodes" here](https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/blockmanagement/DatanodeAdminDefaultMonitor.java#L296)
### How was this patch tested?
All "TestDecommission" & "DatanodeAdminManager" tests pass when run locally
Same manual testing from https://github.com/apache/hadoop/pull/3675 applies.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
- [n/a ] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
- [n/a] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [n/a] If applicable, have you updated the `LICENSE`, `LICENSE-binary`, `NOTICE-binary` files?
