Exception while loading metadata of hive table.
Hi All,
I am getting following exception while loading metadata of hive table
*java.io.IOException:
MetaException(message:java.lang.ClassNotFoundException Class
org.openx.data.jsonserde.JsonSerDe not found)*

while i have added the required jar in tomcat
tomcat/webapps/kylin/WEB-INF/lib folder. it shows in class path of running
java program too and jar contain the above mentioned class in exception.
*jar -xvf /usr/lib/hive/lib/json-serde-1.3-jar-with-dependencies.jar | grep
'org.openx.data.jsonserde.JsonSerDe'*
* inflated: org/openx/data/jsonserde/JsonSerDe$1.class*
inflated: org/openx/data/jsonserde/JsonSerDe.class
Any Idea??
Re: Exception while loading metadata of hive table.

Kylin doesn¹t depend on this lib; Seems hive didn¹t find the class and
then throw the exception (embedded in MetaException); You may need check
your Hive configuration; Google this error there are several discussions
on this;
