unable to create cluster

[krithikagopalakrishnan]

Hi all,
im trying to get to know the rocksplicator setup. I configured the docker and trying to create a new cluster and im getting connection time out error.

 No handlers could be found for logger "kazoo.client"
 Traceback (most recent call last):
  File "rocksdb_admin.py", line 114, in <module>
     zk_client = _get_zk_client()
   File "rocksdb_admin.py", line 110, in _get_zk_client
     c.start()
   File "/usr/local/lib/python2.7/dist-packages/kazoo/client.py", line 567, in start
     raise self.handler.timeout_exception("Connection time-out")
 kazoo.handlers.threading.KazooTimeoutError: Connection time-out
 

i guess im missing something very basic.
can someone help me in this..?

Did you have the correct ZK cluster address specified in the script?

Thanks @newpoo there was a typo in zk cluster address. Not sure how i overlooked it.
Now the rocksdb_admin.py script runs successfully.
To understand the replication setup, im trying to run the counter service example. I landed into the following error,

Am i missing anything here? Anyother configuration has to be done beforehand??
Thanks in advance

Can you try to pass the config file to --shard_config_path?
The cluster needs this config file to know how to route traffic from clients.

Hi @newpoo The server runs now. Now Im trying to write a small client program.
In that, Im creating a replicator instance and adding a db.
When i try to compile im getting the following error,

../../rocksdb_replicator/librocksdb_replicator.a(replicated_db.cpp.o):(.data.rel.ro+0x10): undefined reference to `typeinfo for rocksdb::WriteBatch::Handler'
collect2: error: ld returned 1 exit status

What am i missing here?
Also, Through the client program, if i insert a batch, how does it gets replicated between shards?? Can u explain how replication occurs?

What build system do you use? cmake?
