@Mohd Azhar

You are getting the error showing the following message:

TezUncheckedException: Invalid configuration of tez jars, tez.lib.uris is not defined

So can you please check and share the "tez.lib.uris" property to the above file location under Ambari > Hive configs > (custom hive-site) is it pointing to correct tar file? Example:

tez.lib.uris = /hdp/apps/${hdp.version}/tez/tez.tar.gz

- Also please check if the path for the "tez-site.xml" is added in the "webhcat-site.xml" in Hive configs as following or not:

templeton.libjars=/usr/hdp/${hdp.version}/zookeeper/zookeeper.jar,/usr/hdp/${hdp.version}/hive/lib/hive-common.jar/,/etc/tez/conf/tez-site.xml

.
