-------------------------------
Summary: Code Cleanup in DFSInputStream
Key: HDFS-8280
URL: https://issues.apache.org/jira/browse/HDFS-8280
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Jing Zhao
Assignee: Jing Zhao
Priority: Minor
This is some code cleanup separate from HDFS-8272:
# Avoid duplicated block reader creation code
# If no new source DN can be found, {{getBestNodeDNAddrPair}} returns null
instead of throwing Exception. Whether to throw Exception or not should be
determined by {{getBestNodeDNAddrPair}}'s caller.
