The zookeeper exception was thrown by the server when it could not get a lock on the zookeeper’s database.
It’s easy to forget that zookeepers are a crucial part of our daily life too. We know that after 10 years of having a zookeeper, we still want to use it to share information with each other. So we should be really happy to hear that Arkane’s new zkclient has some new features that let us still use the original in a more powerful way.
I think it’s great that Arkane has finally done something to make it easier for users to set up zkclients. What they’ve done is created a new class of “zookeeper” (zookeeper is the name for a database that manages the zookeeper database in a distributed manner).
There are two zookeeper classes: One for zookeeper and one for zookeeper-client. The second is for zkclient.
It’s easy to understand why they’ve decided to build one. The first thing they need to do is they need to create a new database containing all the zookeeper classes and add a new class of zookeeper-client zookeeper-client zookeeper. This new database will keep track of all the various zookeeper classes that are currently in the database.
So to put it bluntly, the java.io.IOException when adding the zookeeper-client zookeeper-client zookeeper zookeeper to the database is because they didnt know how to add all the zookeeper classes without the database getting out of sync.
I know, that’s a really neat way to organize a database, but that’s a little bit of a story to tell. If you add a new class of zookeeper-client zookeeper zookeeper zookeeper-client zookeeper-client zookeeper to the database, it will be the same class that has been added to the database.
The other issue is that when you do that, java.io.IOException will be thrown, which is basically the same as when you execute a class in the same jar.
So what you need to do is either check the classpath or the class files in the jar if you’re using the class path. If you’re using the class files, they have to be the same version of the jar. So you can either use the classfiles or the jar files. But if you add the jar files, then you will get a different class.
