Subject [jira] [Resolved] (HDFS-4394) QJM client tests require a bit more time in some environments
Date Mon, 14 Jan 2013 02:54:12 GMT

]

Andrew Purtell resolved HDFS-4394.
----------------------------------

    Resolution: Invalid

Closing as invalid. Sorry for the noise. I didn't realize these tests complete in mere seconds
normally. Something is really off in this dev environment.

SE Runtime Environment (build 1.6.0_37-b06), Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01,

> I see hard timeouts of TestQuorumJournalManager and TestQJMWithFaults locally on a dual
core laptop. Frequent jstacking shows some minor delay in IPv4 address<->local hostname
resolution. These tests start up new "daemons" frequently enough for this to be an issue.
> With the patch applied, these tests pass. 
> I've made a few tries at improving the behavior of the resolver: I've of course insured
the 'hosts' file does not have entries which interfere, checked nsswitch.conf sanity, as well
as experimented with toggling the java.net.preferIPv4 system property, finally reconfigured
dnsmasq to serve local forward and reverse entries, still need the patch. Perhaps I've overlooked
another option?
