bbeaudreault opened a new pull request #3527:
URL: https://github.com/apache/hadoop/pull/3527


   ### Description of PR
   
   Refactor refreshing of cached block locations so that it happens as part of 
an async process, with rate limiting. Add the ability to limit to only refresh 
DFSInputStreams if necessary. This defaults to false to preserve backwards 
compatibility with the old behavior from 
https://issues.apache.org/jira/browse/HDFS-15119
   
   See https://issues.apache.org/jira/browse/HDFS-16262
   
   ### How was this patch tested?
   
   I added a new test class TestLocatedBlocksRefresher. I am in the process of 
deploying this internally on one of our hadoop-3.3 clusters, will report back.
