For this block, it's sort of modeled after other examples in DFSClient, such [as initializing the striped read thread pool](https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSClient.java#L3150). I think the idea is that DFSClient could easily be used in multiple threads, so we want to avoid double initializing the shared resource. -- This is an automated message from the Apache Git Service.
