------------------------------------------
Summary: avoid annoying log message when dfs.domain.socket.path is
not set
Key: HDFS-4440
URL: https://issues.apache.org/jira/browse/HDFS-4440
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
Priority: Trivial
When dfs.domain.socket.path is not set, it gets set to the empty string. We
should if this conf key is the empty string in {{DomainSocketFactory}}, rather
than checking against null as we currently do. Otherwise, we get annoying log
messages about failing to connect to the UNIX domain socket at ''.
