"Distributed system's manager"
5/5
What do you like best about ZooKeeper?

It is a very good tool/platform for managing a distributed system it provides all the capability required like observe the servers and reelect masters when master node goes down it also has persistent data service though its not a database it has data specific to zk, its a small storage Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

There is nothing specific but its little difficult to debug, when we want to delete some nodes there are multiple places we need to delete Review collected by and hosted on G2.com.

"My own experience with Zookeeper for 4 years"
4/5
What do you like best about ZooKeeper?

ZooKeeper is a really cool technology for working with shared configuration and cloud management. It's a very lightweight service and its working without downtimes and maintenance, and it's a very big benefit. The best thing that I like that it's very simple in use and very simple for understanding. Zookeeper just works :) And it doesn't matter if it's working with a cloud of 2 servers or with a cloud of thousands. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

There are some things that may be better. First, there is no User Interface for working with the directory tree. All of the management with Zookeeper service like (uploading / deleting / creating) goes through CMD. For each command, we made a script and it's such an annoying thing, and really dangerous because of the big count of params that need to be passed through CMD. There is no option to know what's going on with your Zookeeper without using some 3rd party program (We made it by ourselves https://github.com/Bazger/SolrAdministrationToolKit), for example, to know the sequence of files on the tree or what kind of file was uploaded or which folders are created. Same thing for uploading and deleting files. The main problem is that there are no interesting logs so it's really hard to understand and resolve any kind of problem with Zookeeper if it happens. All uploaded files and dirs to the service are saved as one big file on the VM. So there is no option to get saved data from Zookeeper without sending an HTTP command to the service, and there is no option to recover the data if the service is down.

"As the name says, it does exactly same by managing multiple applications."
5/5
What do you like best about ZooKeeper?

It serves as a metadata storage layer to store configuration information and makes the management of distributed systems very easy. It is highly reliable and fault-tolerant. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

I never face any serious issues with zookeepers, but the CLI part can be made better to support more commands. Review collected by and hosted on G2.com.

"The ultimate master in coordination"
4/5
What do you like best about ZooKeeper?

We used Zookeeper for coordinating between various application instances many years ago for building a group membership protocol. It is an excellent tool and forms the backbone of most modern day distributed systems, Kafka being one of the most well known ones. The way it handles state machine replication using Zab makes it a tool of choice for anyone who wants to use it for a variety of use cases like leader election, resource ownership etc. All in all, a great product. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

Zookeeper has a steep learning curve and one really needs to spend a lot of time to understand ZK to use it to build any meaningful tools. Review collected by and hosted on G2.com.

"Zookeeper is helps me throughout the project to manage all the services among clusters"
4/5
What do you like best about ZooKeeper?

Zookeeper manages all the distributed services. Since our use case has readability a lot so zookeeper is best for this. It reacts to requests fast. We run a performance monitoring SaaS that often Zookeeper monitoring and its typical for SREs to use it together for solr, Kafka, hadoop etc. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

Its has a limited support to cross cluster scenarios and it is pretty heavy. Adding new zookeeper service will lead to data loss. Migration is not possible without user intervention. Review collected by and hosted on G2.com.

"Zookeeper experience has been amazing."

The cluster management in a distributed Kafka cluster. The service discovery of the kafka brokers and leader election has always been spot on. Never faced any difficulties with it. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

I have never had any issues with Zookeeper in a Kafka cluster, it has always performed well. Review collected by and hosted on G2.com.

"Configuration Management Tool"
4.5/5
What do you like best about ZooKeeper?

Zookeeper is a distributed config management tool. It is very useful in our project when storing all static configurations values. For example the database username and password. These credentials should not be stored in the application itself if you need to secure the database. You only need to get the key during run-time the application is running. But you need to have a zookeeper client to access from your application to connect zookeeper server instance. Therefore I recommend this tool as part of your application architecture design.

What do you dislike about ZooKeeper?

No comment at this time I haven't issues encountered yet. Review collected by and hosted on G2.com.

It's easy to use and can track job timing and clusters' performance, and the important part is to manage cluster jobs with the help of Apache Zookeeper. Review collected by and hosted on G2.com.

Sometimes I receive an error stating that the file is missing or a message about a version upgrade. Review collected by and hosted on G2.com.

"Good for distribution system"
4.5/5
What do you like best about ZooKeeper?

I'm using it for my batch processing services. Zookeeper tracks all the instances and manages which instance processes which batch. Also, it tracks the instance registry and deregistry. It is working fine with my use case. Also, it works great with the Kafka cluster. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

There is nothing to dislike about Zookeeper, but there is always hope for improvement. Review collected by and hosted on G2.com.
