Subject [jira] [Updated] (HDFS-3166) Hftp connections do not have a timeout
Date Tue, 03 Apr 2012 16:36:23 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3166?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daryn Sharp updated HDFS-3166:
------------------------------

    Attachment: HDFS-3166.patch

Linux considers the requested listen backlog as "advisory"...  It rounds it up to the next
power of 2, with a floor of 16.  I modified the test to try up to 32 times to trigger a connect
timeout.

when there is a network outage during which time the remote host closed the socket.
