---------------------------------
Summary: Hedged read might hang infinitely if read data from all
DN failed
Key: HDFS-11303
URL: https://issues.apache.org/jira/browse/HDFS-11303
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 3.0.0-alpha1
Reporter: Chen Zhang
Hedged read will read from a DN first, if timeout, then read other DNs
simultaneously.
If read all DN failed, this bug will cause the future-list not empty(the first
timeout request left in list), and hang in the loop infinitely
