Permission denied as zookeeper user

Hello everyone, I have a little problem when I try to launch "./zkServer.sh start" with my "zookeeper" user ... I get the following stacktrace: 2018-07-17 18:26:53,569 [myid:5] - INFO [WorkerReceiver[myid=5]:FastLeaderElection@600] - Notification: 1 (message format version), 3 (n.leader),

Re: Zookeeper consistency

>> I think that Zookeeper is linearable only if there are only write operation. Yes writes are linearizable because writes are totally ordered globally. For read, a linearizable read needs to read the latest writes in the system at the point in time the read is issued; so by this definition, ZK

Re: Permission denied as zookeeper user

Hi Adrian, Check the ‘dataDir’ and ‘dataLogDir’ (might be the same) directory permissions. Zookeeper running user must have write permissions to them. Regards, Andor > On 2018. Jul 17., at 18:39, adrien ruffie wrote: > > Hello everyone, > > > I have a little problem when I try to launch

Re: Problem with ZK log files and snapshots

If your transactions are short lived (something like you are taking a lock and then releasing it), you will find that “containers” holding these locks are not cleaned by Zookeeper. This in turn will make snapshot files big and will cause all sorts of issues. I found myself in that situation few

Zookeeper consistency

hi, I am reading the old thread of http://comments.gmane.org/gmane.comp.java.hadoop.zookeeper.user/5221. I have 2 questions. Question 1: I agree with Zookeeper is sequential consistency, but I don't think Zookeeper is linearizability even if doing sync+read for every read.  for example,

Re: ZooKeeper Cluster Health Checking

Hi Adrien, Take a look at monitoring in src/contrib/monitoring - it does what you would like to achieve, in python. Read the README for more information: https://github.com/apache/zookeeper/tree/master/src/contrib/monitoring If this one is not good for you, you can use JMX to query MBeans. A
