------------------------------------
Summary: QJM client tests require a bit more time in some
environments
Key: HDFS-4394
URL: https://issues.apache.org/jira/browse/HDFS-4394
Project: Hadoop HDFS
Issue Type: Improvement
Components: namenode, test
Affects Versions: 3.0.0, 2.0.3-alpha
Environment: Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-35-generic x86_64),
Java(TM) SE Runtime Environment (build 1.6.0_37-b06), Java HotSpot(TM) 64-Bit
Server VM (build 20.12-b01, mixed mode)
Reporter: Andrew Purtell
Priority: Trivial
Attachments: HDFS-4394.patch
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.IPv4
system property, finally reconfigured dnsmasq to serve local forward and
reverse entries, still need the patch. Perhaps I've overlooked another option?
