windows ZK client port
Hi all, We have created a windows native port for the C ZK client. We've done our own testing and it all seems to work, and we'd like to contribute it back to the community. However, porting the existing unit tests to windows has proven to be incredibly difficult. It's not clear that we have the bandwidth here to do that port ourselves. What should we do with this code? If we created windows unit tests would the project have windows hardware to run them on? Thanks, Camille

Overall logic remained the same; changes were mainly due to recent client-side code refactorings, e.g. move code from ClientCnxn to ClientCnxnSocket.

I promised to look into this, but I haven't had time to do it. I'll try to
spend some time on this next week.

Zookeeper drops connections under moderate IO load
--
Key: ZOOKEEPER-885
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-885
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.2.2, 3.3.1
Environment: Debian (Lenny)
1Gb RAM
swap disabled
100Mb heap for zookeeper
Reporter: Alexandre Hardy
Priority: Critical
Fix For: 3.4.0
Attachments: WatcherTest.java, benchmark.csv, tracezklogs.tar.gz,
tracezklogs.tar.gz, zklogs.tar.gz
A zookeeper server under minimum load, with a number of clients watching
exactly one node will fail to maintain the connection when the machine is
subjected to moderate IO load.
In a specific test example we had three zookeeper servers running on
dedicated machines with 45 clients connected, watching exactly one node. The
clients would disconnect after moderate load was added to each of the
zookeeper servers with the command:
{noformat}
dd if=/dev/urandom of=/dev/mapper/nimbula-test
{noformat}
The {{dd}} command transferred data at a rate of about 4Mb/s.
The same thing happens with
{noformat}
dd if=/dev/zero of=/dev/mapper/nimbula-test
{noformat}
It seems strange that such a moderate load should cause instability in the
connection.
Very few other processes were running, the machines were setup to test the
connection instability we have experienced. Clients performed no other read
or mutation operations.
Although the documents state that minimal competing IO load should present on
the zookeeper server, it seems reasonable that moderate IO should not cause
problems in this case.

[jira] Updated: (ZOOKEEPER-938) support Kerberos Authentication
[ https://issues.apache.org/jira/browse/ZOOKEEPER-938?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Eugene Koontz updated ZOOKEEPER-938: Attachment: ZOOKEEPER-938.patch support Kerberos Authentication --- Key: ZOOKEEPER-938 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-938 Project: ZooKeeper Issue Type: New Feature Components: server Reporter: Eugene Koontz Assignee: Eugene Koontz Fix For: 3.4.0 Attachments: NIOServerCnxn.patch, ZOOKEEPER-938.patch, jaas.conf, sasl.patch Support Keberos authentication of clients. The following usage would let an admin use Kerberos authentication to assign ACLs to authenticated clients. 1. Admin logs into zookeeper (not necessarily through Kerberos however). 2. Admin decides that a new node called '/mynode' should be owned by the user 'zkclient' and have full permissions on this. 3. Admin does: zk create /mynode content kerb:zkcli...@foofers.org:x:cdrwa (note: for now, the dummy ':x' is a placeholder for the password, and is required by the zk command parser. The user's actual password is not stored within Zookeeper; simply put 'x' there.) 4. User 'zkclient' logins to kerberos using the command line utility 'kinit'. 5. User connects to zookeeper server using a Kerberos-enabled version of zkClient (ZookeeperMain). 6. Behind the scenes, the client and server exchange authentication information. User is now authenticated as 'zkclient'. 7. User accesses /mynode with permissions 'cdrwa'. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
Re: New to ZooKeeper project
Hi, I am reading the given guidance in the ZooKeeper website and still I do not have a good idea of what is done by ZooKeeper?. I need to know for what kind of applications does ZooKeeper is used and how it is used? Can someone help me to move forward? thanks.
