Runaway thread - Zookeeper inside Eclipse
-----------------------------------------
Key: ZOOKEEPER-863
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-863
Project: Zookeeper
Issue Type: Bug
Affects Versions: 3.3.0
Environment: Linux; x86
Reporter: Stephen McCants
Priority: Critical
I'm running Zookeeper inside an Eclipse application. When I launch the
application from inside Eclipse I use the following arguments:
-Dzoodiscovery.autoStart=true
-Dzoodiscovery.flavor=zoodiscovery.flavor.centralized=localhost
This causes the application to start its own ZooKeeper server inside the
JVM/application. It immediately goes into a runaway state. The name of the
runaway thread is "NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181". When I suspend
this thread, the CPU usage returns to 0. Here is a stack trace from that
thread when it is suspended:
EPollArrayWrapper.epollWait(long, int, long, int) line: not available [native
method]
EPollArrayWrapper.poll(long) line: 215
EPollSelectorImpl.doSelect(long) line: 77
EPollSelectorImpl(SelectorImpl).lockAndDoSelect(long) line: 69
EPollSelectorImpl(SelectorImpl).select(long) line: 80
NIOServerCnxn$Factory.run() line: 232
Any ideas what might be going wrong?
Thanks.
