reconfig command in Zookeeper 3.5.0 Alpha

Hi,

I downloaded 3.5.0 Alpha release of Zookeeper. I was wondering how Zookeeper is reconfigured if new server is added and old is deleted.
The Zookeeper document (book) talks about it and how to use it in release 3.5.0 of Zookeeper. Could someone please tell me when that feature is going to be available as I could not find "reconfig" command in downloaded software package.

Thanks,
Subodh

Hi Alex,

When I tried reconfig command on server 2 in the following format then it works.

[zk: localhost:2181(CONNECTED) 3] reconfig -members server.1=10.3.1.130:2780:2782,server.2=10.3.1.131:2780:2783
Committed new configuration:
server.1=10.3.1.130:2780:2782:participant
server.2=10.3.1.131:2780:2783:participant
version=20000000d

Thanks,
Subodh

Hi Alex,

I am still getting the same error. This time I started server 1 with following contents in dynamicConfigFile

server.1=10.3.1.130:2780:2783

Then I started server 2 with the following contents in dynamicConfigFile as you suggested.

server.1=10.3.1.130:2780:2783
server.2=10.3.1.131:2780:2783

After starting server 2, I see dynamic config file contents of server 2 change to that of server 1.

The on server 1, I tried the following command using zkCli.sh

reconfig -add serverId=10.3.1.131:2780:2783

But I still get the following error message.

KeeperErrorCode = MarshallingError for

Here is the output of zkCli.sh on server 1

[zk: localhost:2181(CONNECTED) 3] config server.1=10.3.1.130:2780:2783:participant
version=200000000
[zk: localhost:2181(CONNECTED) 4] reconfig -add serverId=10.3.1.131:2780:2783 KeeperErrorCode = MarshallingError for
[zk: localhost:2181(CONNECTED) 5]  .

I tried the same command on server 2, but still I get the same result. Here is the output of zkCli.sh on server 2.

[zk: localhost:2181(CONNECTED) 0] config server.1=10.3.1.130:2780:2783:participant
version=200000000
[zk: localhost:2181(CONNECTED) 1]  reconfig -add serverId=10.3.1.131:2780:2783 KeeperErrorCode = MarshallingError for
[zk: localhost:2181(CONNECTED) 2]

Thanks,
Subodh

Hi,

Your initial config files are defining two ZooKeeper clusters of size 1.
They are independent and will not try to connect.
Instead, when defining the config of server 2 you should add both a line for server 1 and a line for server 2 (this is an invalid config, used just to initialize server 2). This way server 2 will try to connect to server 1. Once connected to server 1, it will update its config file to the one at server 1 (since this is the valid current configuration). Then you can add server 2 using reconfig and both servers should have both of them in the config.

RE: reconfig command in Zookeeper 3.5.0 Alpha

Posted by Subodh Garg-SSI <su...@ssi.samsung.com>.

Alex,

Sorry for the trouble.
Yes, it worked fine. The syntax is slightly different from adding a new server. Just specifying -remove <serverid> is enough.

Thanks,
Subodh

Subodh, please read the user manual to get command syntax right.

RE: reconfig command in Zookeeper 3.5.0 Alpha

Posted by Subodh Garg-SSI <su...@ssi.samsung.com>.

Hi Alex,

The server remove is not working if I remove it after adding it.

[zk: localhost:2181(CONNECTED) 0]  reconfig -add server.3=10.3.1.132:2780:2782;2181
Committed new configuration:
server.1=10.3.1.130:2780:2782:participant;0.0.0.0:2181
server.2=10.3.1.131:2780:2782:participant;0.0.0.0:2181
server.3=10.3.1.132:2780:2782:participant;0.0.0.0:2181
version=800000007

I verified the config on server 1 and server 2 and it showed updated config.
After that I tried to remove server 3 from server 3 zkCLI but I am getting the following error.

[zk: localhost:2181(CONNECTED) 1]  reconfig -remove server.3=10.3.1.132:2780:2782;2181
KeeperErrorCode = MarshallingError for 
[zk: localhost:2181(CONNECTED) 2]

Thanks

Thanks a lot! That’s exactly what was missing. It worked after specifying client port to the command.

[zk: localhost:2181(CONNECTED) 0] reconfig -add server.2=10.3.1.131:2780:2783;2181
Committed new configuration:
server.1=10.3.1.130:2780:2782:participant

I think you have to add a client port at the end, like this:

reconfig -add server.5=125.23.63.23:1234:1235;1236

Thanks a lot! That’s exactly what was missing. It worked after specifying client port to the command.

[zk: localhost:2181(CONNECTED) 0] reconfig -add server.2=10.3.1.131:2780:2783;2181

I think you have to add a client port at the end, like this:

reconfig -add server.5=125.23.63.23:1234:1235;1236

RE: reconfig command in Zookeeper 3.5.0 Alpha

Posted by Subodh Garg-SSI <su...@ssi.samsung.com>.

I tried the following on server 2, but it fails with a different error.

[zk: localhost:2181(CONNECTED) 0] config
server.1=10.3.1.130:2780:2782:participant
version=300000000
[zk: localhost:2181(CONNECTED) 1] reconfig -add server.2=10.3.1.131:2780:2783
KeeperErrorCode = BadArguments for

Thanks,
Subodh

RE: reconfig command in Zookeeper 3.5.0 Alpha

Posted by Subodh Garg-SSI <su...@ssi.samsung.com>.

Hi Alex,

I am still getting the same error. This time I started server 1 with following contents in dynamicConfigFile

server.1=10.3.1.130:2780:2783

Then I started server 2 with the following contents in dynamicConfigFile as you suggested.

server.1=10.3.1.130:2780:2783
server.2=10.3.1.131:2780:2783

After starting server 2, I see dynamic config file contents of server 2 change to that of server 1.

The on server 1, I tried the following command using zkCli.sh

reconfig -add serverId=10.3.1.131:2780:2783

But I still get the following error message.

KeeperErrorCode = MarshallingError for

Here is the output of zkCli.sh on server 1

[zk: localhost:2181(CONNECTED) 3] config
server.1=10.3.1.130:2780:2783:participant
version=200000000
[zk: localhost:2181(CONNECTED) 4] reconfig -add serverId=10.3.1.131:2780:2783
KeeperErrorCode = MarshallingError for 
[zk: localhost:2181(CONNECTED) 5]  .

I tried the same command on server 2, but still I get the same result. Here is the output of zkCli.sh on server 2.

[zk: localhost:2181(CONNECTED) 0] config
server.1=10.3.1.130:2780:2783:participant
version=200000000
[zk: localhost:2181(CONNECTED) 1]  reconfig -add serverId=10.3.1.131:2780:2783
KeeperErrorCode = MarshallingError for 
[zk: localhost:2181(CONNECTED) 2]

Thanks,
Subodh

Hi,

Your initial config files are defining two ZooKeeper clusters of size 1.
They are independent and will not try to connect.
Instead, when defining the config of server 2 you should add both a line for server 1 and a line for server 2 (this is an invalid config, used just to initialize server 2). This way server 2 will try to connect to server 1. Once connected to server 1, it will update its config file to the one at server 1 (since this is the valid current configuration). Then you can add server 2 using reconfig and both servers should have both of them in the config.

Re: reconfig command in Zookeeper 3.5.0 Alpha

Posted by Alexander Shraer <sh...@gmail.com>.

Hi,

Your initial config files are defining two ZooKeeper clusters of size 1.
They are independent and will not try to connect.
Instead, when defining the config of server 2 you should add both a line
for server 1 and a line for server 2 (this is an invalid config,
used just to initialize server 2). This way server 2 will try to connect to
server 1. Once connected to server 1, it will
update its config file to the one at server 1 (since this is the valid
current configuration). Then you can add server 2 using reconfig and both
servers should have both of them in the config.

RE: reconfig command in Zookeeper 3.5.0 Alpha

Posted by Subodh Garg-SSI <su...@ssi.samsung.com>.

Alex,

I am running zkServer.sh on two servers with IP address as 10.3.1.130 and 10.3.1.131. I declared standaloneEnabled=false in the zoo.cfg file for each of the server. I also created a "dynamicConfigFile="  parameter in each server's static config file. In dynamic config file for server 1, I added its own server's IP address entry as server.1=10.3.1.130:2780:2783 for server1. In dynamic config file for server 2, I added its own server's IP address entry as server.2=10.3.1.131:2780:2783. 

After starting Zookeeper server on two machines, I checked they both got elected as LEADER. After that I ran zkCli.sh on server 1 and tried to add server 2 in the following way, but I get "Marshalling Error for".

Is there any problem the way I am adding the server?

Here is what it shows in zkCli.sh on each of the server.

Server 1:
[zk: localhost:2181(CONNECTED) 8] config
server.1=10.3.1.130:2780:2783:participant
version=100000000
[zk: localhost:2181(CONNECTED) 9] reconfig -add serverId=10.3.1.131:2780:2783
KeeperErrorCode = MarshallingError for 
[zk: localhost:2181(CONNECTED) 10]

Server 2:
[zk: localhost:2181(CONNECTED) 2] config
server.2=10.3.1.131:2780:2783:participant
version=100000000
[zk: localhost:2181(CONNECTED) 3]

Thanks
Subodh

Hi Alex,

Thanks for pointing me to the documentation for 3.5.0. Could you point me to the 3.5.0 code as well?

I do not see the 3.5.0 release listed on the following page for downloading  Zookeeper.

http://zookeeper.apache.org/releases.html#download

I could find only 3.5.0 Alpha release but not 3.5.0. 

Thanks
Subodh
