[jira] [Commented] (ZOOKEEPER-1506) Re-try DNS hostname -> IP resolution if node connection fails

[~ekoontz] Good prediction -- your patch *significantly* improved things for me!
[~mahadev] Even with Eugene's patch, some tests failed for me. I'm attaching
summary as well as the logs. I also ran tests without his patch but they're
still not done (45 min and counting) and many many of them have already failed
(many of which passed with Eugene's patch). In summary, +2 for the patch! But
we should still investigate the remaining failures.

Will do. How long should the tests be expected to run for? The last time I ran
ZK tests (few days ago), they didn't run to completion even after 30 minutes,
at which point I killed the run.

[~mahadev] Happy to test though I'm pretty sure this is unrelated to
ZOOKEEPER-1550 -- recall that I'm using Oracle JDK (not OpenJDK) and I'm on
Mac. I haven't been able to ever successfully run ZK tests on a Mac with JDK7
(starting with 7u3, now on 7u7). Things were broken with ZK 3.4.3 and have just
become worse with 3.4.4. Will report back shortly with the patch in 1550.

Update:
* With JDK 7u7 on Mac and ZK 3.4.3, I don't see the ConnectionLoss exceptions
anymore (rather I haven't yet observed them)
* With JDK 7u7 on Mac and ZK 3.4.4, I see even more ConnectionLoss exceptions
than before :-/

Scott: I've only tested this on my Mac and it happens fairly reliably. We have
a few other Mac users who can also hit this.
On a related note, one of my colleagues also ran into some failures on Linux,
but it's not clear if the root cause was the same.

Patrick: I believe the jenkins job runs on Linux. I'm running Java7 on Mac
natively. Resources are not an issue: my machine as 8G of memory, runs on SSDs
and there's no virtualization in the picture.

[jira] [Created] (ZOOKEEPER-1477) Test failures with Java 7
Diwaker Gupta created ZOOKEEPER-1477:
Summary: Test failures with Java 7
Key: ZOOKEEPER-1477
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1477
Project: ZooKeeper
Issue Type: Bug
Components: server, tests
Affects Versions: 3.4.3
Environment: Mac OS X Lion (10.7.4)
Java version:
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b21)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)
Reporter: Diwaker Gupta
Priority: Critical
I downloaded ZK 3.4.3 sources and ran {{ant test}}. Many of the tests failed,
including ZooKeeperTest. A common symptom was spurious
{{ConnectionLossException}}:
{code}

As background, I was actually investigating some non-deterministic failures
when using Netflix's Curator with Java 7 (see
https://github.com/Netflix/curator/issues/79). After a while, I figured I
should establish a clean ZK baseline first and realized it is actually a ZK
issue, not a Curator issue.
We are trying to migrate to Java 7 but this is a blocking issue for us right
now.
