Hi krishna,
I guess that you set EMR to use AWS Glue catalog as Hive metadata and Kylin
is missing the AWS lib com.amazonaws.glue in Kylin's classpath. You should find
the lib in the EMR cluster and add it to your class path(maybe $KYLIN_HOME/lib)
is OK.
If you cannot find the right jar, you may package it manually, repo should
be this
https://github.com/awslabs/aws-glue-data-catalog-client-for-apache-hive-metastore.
Maybe ask EMR customer service for help should be considered.
