Todd Lipcon created HDFS-3548:
---------------------------------
Summary: NamenodeFsck.copyBlock fails to create a Block Reader
Key: HDFS-3548
URL: https://issues.apache.org/jira/browse/HDFS-3548
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 2.0.0-alpha, 0.23.1
Reporter: Todd Lipcon
Priority: Critical
NamenodeFsck.copyBlock creates a Socket using {{new Socket()}}, and thus that
socket doesn't have an associated Channel. Then, it fails to create a
BlockReader since RemoteBlockReader2 needs a socket channel.
