I can suggest 3 options 1. you can use JUnit test to test your UDF (e.g. TestGenericUDFLastDay)
2. you can create q file and test your UDF via mvn (look at udf_last_day.q) mvn clean install -DskipTests -Phadoop-2 cd itest/qtest mvn test -Dtest=TestCliDriver -Dqfile=udf_last_day.q -Dtest.output.overwrite=true -Phadoop-2 3. you can build hive with dist profile and run hive cli locally mvn clean install -DskipTests -Phadoop-2,dist cd packaging/target/apache-hive-1.2.0-SNAPSHOT-bin/apache-hive-1.2.0-SNAPSHOT-bin/ bin/hive Maybe you can run hive using local engine but I decided to have hdfs and yarn running locally After you have hdfs and yarn running locally you can create hive-site.xml similar to the following sample hive config $ echo $HIVE_CONF_DIR /etc/hive/apivovarov-conf $ cat /etc/hive/apivovarov-conf/hive-site.xml <?xml version="1.0" encoding="UTF-8" standalone="no"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>hive.metastore.warehouse.dir</name> <value>hdfs://localhost/apps/apivovarov/warehouse</value> </property> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:derby:;databaseName=/tmp/apivovarov_metastore_db;create=true</value> </property> </configuration> On Wed, Apr 1, 2015 at 10:14 AM, Alex Bohr <a...@gradientx.com> wrote: > Hi, > I'm developing a new UDF. > I want to be able to test the new jar as I develop without having to copy > the Jar up to HDFS every time I change code and recompile the Jar. > > I'm using Hive CLI for testing, and adding this command: > add jar 'file:///home/abohr/test/hive-udf-1.0-SNAPSHOT.jar'; > > I've also used variations on the local file system protocol: > add jar 'file://home/abohr/test/hive-udf-1.0-SNAPSHOT.jar'; > add jar 'file:/home/abohr/test/hive-udf-1.0-SNAPSHOT.jar'; > add jar '/home/abohr/test/hive-udf-1.0-SNAPSHOT.jar'; > > but keep getting this error: > Query returned non-zero code: 1, > cause: '/home/abohr/test/hive-udf-1.0-SNAPSHOT.jar' does not exist. > > Is it not possible to test UDFs with a jar on the local filesystem? > I don't want to add the jar to our configured aux-jars path that > HiveServer2 reads from until I'm done testing. > > > Thanks >
