Subject [jira] [Updated] (HBASE-5197) [replication] Handle socket timeouts in ReplicationSource to prevent DDOS
Date Mon, 13 Feb 2012 22:16:59 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5197?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jean-Daniel Cryans updated HBASE-5197:
--------------------------------------

    Attachment: HBASE-5197.patch

Adding the handling of the exception with a sleep of 100 seconds by default. In my testing
this has prevented DDOSing.

> Kind of like HBASE-4462 but for replication. If while replicating you get a socket timeout,
the last thing you want to do is to retry it right away. Since we can't fail the replication
thread, the best I can think of is to sleep a really long amount of time.
> Planning to bring this to all branches.
