Hi,

Please make sure that zookeeper JAR is located in your HBase installation at "/usr/local/hbase-X.XX./lib".

Hi Sabrina,

Thanks for replying.

I have already placed the zookeper zar in the specified location but still the error persists.

Could there be any possibility of any other error which i am not able to locate.

and one more thing, i am using talend open studio for big data.

Do I need to have enterprise version for the same.

thanks

Hello,

Can you successfully connect to HBase through client without using talend tool?

Please take a look at this page about 'Compare all bigdata products ':https://www.talend.com/products/big-data/big-data-compare-all/?_ga=2.20052987.2137201197.1505701364-1289787410.1496918705 to right size your solution.

Best regards

Sabrina

Hi,

Is there any extra component in your 'Designer' space? Would you mind posting your current job setting screenshots into forum which will be helpful for us to address your issue?

Thank for your time.

Best regards

Sabrina
