[jira] [Created] (HDFS-3068) RemoteBlockReader2 fails when using SocksSocketFactory

RemoteBlockReader2 fails when using SocksSocketFactory 
-------------------------------------------------------

                 Key: HDFS-3068
                 URL: https://issues.apache.org/jira/browse/HDFS-3068
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 0.23.1
            Reporter: Tom White


When hadoop.rpc.socket.factory.class.default is set to org.apache.hadoop.net.SocksSocketFactory, HDFS file reads fail with errors like

{noformat}
Socket Socket[addr=/10.12.185.132,port=50010,localport=55216] does not have an associated Channel.
{noformat}

The workaround is to set dfs.client.use.legacy.blockreader=true to use the old implementation of RemoteBlockReader. RemoteBlockReader should not be removed until this bug is fixed.
