zookeeper + Kafka - Unable to create data director

Question

I´m using zookeeper 3.4.8 in single node and try to use kafka.

When I run this command:

zookeeper-server-start.sh /usr/local/kafka_2.9.2-0.8.2.2    /config/zookeeper.properties

I get the below error:

[2016-02-22 17:32:41,661] ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)
java.io.IOException: Unable to create data directory /var/zookeeper/version-2

Any advice?

Answer 1

I got this problem for this setting on Windows PC:

dataDir=c:/data/zoo/

and thus this error:

2016-12-02 15:29:25,327 [myid:] - ERROR [main:ZooKeeperServerMain@64] - Unexpected exception, exiting abnormally
java.io.IOException: Unable to create data directory ??:\data\zoo\version-2

Problem was solved by changing (I have ZooKeeper on C disk unpackaged)

dataDir=/data/zoo/

Also run command line tool as Administrator if needed

If you're running the zookeeper in the Windows 10 machine we need to specify the dataDir property something like this

"dataDir=C:\zookeeper-3.4.13\data"

Answer 3

Running Kafka on GCE. Simply add sudo and it worked for me.
