Subject [jira] [Commented] (HDFS-3166) Hftp connections do not have a timeout
Date Mon, 02 Apr 2012 22:23:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13244744#comment-13244744
] 

Daryn Sharp commented on HDFS-3166:
-----------------------------------

Last was missing a file, but investigating test failures.  Test creates a listening socket
with a backlog of 1.  It opens a connection to fill the backlog, then tries to open another
to test the connection timeout.  On OS X, the second connect fails as expected, but on linux
the second connect succeeds....

> Hftp connections do not have read timeouts.  This leads to indefinitely hung sockets
when there is a network outage during which time the remote host closed the socket.
> This may also affect WebHdfs, etc.
