> Failed DataNode lookup can crash NameNode with NullPointerException

> Key: HDFS-7225

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.6.0
> Reporter: Zhe Zhang
> Assignee: Zhe Zhang

>
>
> {{BlockManager#invalidateWorkForOneNode}} looks up a DataNode by the
> {{datanodeUuid}} and passes the resultant {{DatanodeDescriptor}} to
> {{InvalidateBlocks#invalidateWork}}. However, if a wrong or outdated
> {{datanodeUuid}} is used, a null pointer will be passed to {{invalidateWork}}
> which will use it to lookup in a {{TreeMap}}. Since the key type is
> {{DatanodeDescriptor}}, key comparison is based on the IP address. A null key
> will crash the NameNode with an NPE.
