Subject [jira] [Commented] (HDFS-4473) don't create domain socket unless we need it
Date Thu, 07 Feb 2013 00:02:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573017#comment-13573017
] 

Aaron T. Myers commented on HDFS-4473:
--------------------------------------

Wow, good to know. What happens if the path is too long? Hopefully there's some decent error.
If not, we might consider checking for this during DN startup.

Regardless, that can be done as a separate JIRA. I'm going to commit this momentarily.

> If {{dfs.domain.socket.path}} is set, but we don't have anything enabled which would
need it (like {{dfs.client.read.shortcircuit}}), don't create the socket.
