I am going through the following lab:
and in paragraph 6.2 (execute a hive query) I am trying to run the following code in Zeppelin: %jbdc(hive) SELECT * FROM riskfactor
When I execute this code I run into the error "prefix not found". What am I doing wrong here. This seems pretty straightforward.
@Robbert Naastepad, could it be the case that the interpreter is not enabled/selected for use in the notebook? See "Configuring a Zeppelin Interpreter" at http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_zeppelin-component-guide/content/using-in....
There is a typo in the code, please change from %jbdc(hive) to %jdbc(hive). Further, for riskfactor table issue can you please drop the riskfactor table first and then recreate it using CTAS. Run the following commands:
drop table riskfactor
In another paragraph,
hiveContext.sql("create table riskfactor as select * from finalresults")
With HDP 2.5 we need to use the jdbc connectors instead of the %sql or hive.
However we had to do the following prior to getting this to work.
in /usr/hdp/current/zeppelin-server/interpreter/jdbc either copy the hive, hadoop and phoenix jars or create soft links for the same
Since all the sample notebooks use the %sql or %hive they would not work.
you will need to use %jdbc(phoenix) or %jdbc(hive) as appropriate.
Once you do this restart the jdbc interpreter
>pwd /usr/hdp/current/zeppelin-server/interpreter/jdbc > ls -l hive-jdbc.jar -> /usr/hdp/current/hive-client/lib/hive-jdbc-1.2.1000.2.5.0.0-1245-standalone.jar hadoop-common.jar -> /usr/hdp/current/hadoop-client/hadoop-common-126.96.36.199.5.0.0-1245.jar phoenix-core-188.8.131.52.5.0.0-1245.jar /usr/hdp/current/phoenix-client/lib/phoenix-core-184.108.40.206.5.0.0-1245.jar
After banging my head against the wall for a while now, Ash's answer was the one I was looking for.
I didn't necessarily get a "%jdbc(hive) prefix not found in Zeppelin". In Zeppelin I got a nondescript error and the logs complaining about java.lang.NoSuchMethodError.
After creating these soft links it worked fine!
i am trying to execute mysql queries, got error prefix not found. when i verified in mysql note there i observer mysql is there instead of %mysql. But unable to add % before mysql, its not editable. can u please help me how can i edit.
