Hbase connectivity problem

Hi,

Using Open Studio for Big Data I am having problems connecting to Hbase.

tHBaseOutput;
Zookeeper quorum: "10.182.14.222"
Zookeeper client port: "2181"

Error Received

Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

I presume its the zookeeper setting I have set incorrectly but can nor see past server/port.

Any help appreciated.

Regards.

Hi,
Did you check zookeeper.znode.parent in zookeeper.znode.parent to see everything is correct? Is there any error logs for Hbase?
Make sure your Hbase DB is list in document TalendHelpCenter0683p000009M9p6.pngupported systems and databases.
