This is a path to a UNIX domain socket that will be used for
|
||||
communication between the DataNode and local HDFS clients, if
|
||||
dfs.client.read.shortcircuit is set to true. If the string "_PORT" is
|
||||
present in this path, it will be replaced by the TCP port of the DataNode.
|
||||
Be careful about permissions for the directory that hosts the shared
|
||||
domain socket; dfsclient will complain if open to other users than the HBase user.
