Chris Nauroth created HDFS-6231: ----------------------------------- Summary: DFSClient hangs infinitely if using hedged reads and all eligible datanodes die. Key: HDFS-6231 URL: https://issues.apache.org/jira/browse/HDFS-6231 Project: Hadoop HDFS Issue Type: Bug Components: hdfs-client Affects Versions: 2.4.0, 3.0.0 Reporter: Chris Nauroth Assignee: Chris Nauroth
When using hedged reads, and all eligible datanodes for the read get flagged as dead or ignored, then the client is supposed to refetch block locations from the NameNode to retry the read. Instead, we've seen that the client can hang indefinitely. -- This message was sent by Atlassian JIRA (v6.2#6252)
