If you have a recent version of Hive (0.13+), you could try registering your UDF as a "permanent" UDF which was added in HIVE-6047: 1) Copy your JAR somewhere on HDFS, say hdfs:///home/nirmal/udf/hiveUDF-1.0-SNAPSHOT.jar. 2) In Hive, run CREATE FUNCTION zeroifnull AS 'com.test.udf.ZeroIfNullUDF' USING JAR 'hdfs:///home/nirmal/udf/hiveUDF-1.0-SNAPSHOT.jar'; The function definition should be saved in the metastore and Hive should remember to pull the JAR from the location you specified in the CREATE FUNCTION call.

Currently I am adding it through Java JDBC code : Statement stmt = null; ResultSet res = null; Connection con = getHiveConnection(host, port, db); try { stmt = con.createStatement(); String[] args = new String[2]; args[0] = "add jar /home/nirmal/udf/hiveUDF-1.0-SNAPSHOT.jar"; args[1] = "CREATE TEMPORARY FUNCTION zeroifnull AS 'com.test.udf.ZeroIfNullUDF'"; for (String queryUDF : args) { stmt.execute(queryUDF); } } Is there any other better way ?
