Key: ZOOKEEPER-1145
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1145
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.4.0
Reporter: Eugene Koontz
Priority: Blocker
Fix For: 3.4.0
Attachments: repeat.sh
Use the attached repeat.sh to run ObserverTest repeatedly by doing:
src/repeat.sh ObserverTest
The test will will fail eventually after a few iterations; should be only a few
minutes.
The line that fails in the test is:
zk = new ZooKeeper("127.0.0.1:" + CLIENT_PORT_OBS,
ClientBase.CONNECTION_TIMEOUT, this);
Attached as out.txt is the output showing a successful run, for comparison,
followed by a failed run.
Note that in the seconds before the test fails, in the following lines, that
there is a 24 second gap in time (between 22:13:02 and 22:13:26):
bq.
