[HDFS-3068] RemoteBlockReader2 fails when using SocksSocketFactory

Description

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

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

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.
