+[Flink Scala Shell]({{ site.baseurl }}/ops/scala_shell.html) is a convenient quick way to try flink.
+You can use hive in scala shell as well instead of specifying hive dependencies in pom file, packaging your program and submitting it via flink run command.
+In order to use hive connector in scala shell, you need to put the following [hive connector dependencies]({{ site.baseurl }}/dev/table/hive/#depedencies) under lib folder of flink dist .
+
+* flink-connector-hive_{scala_version}-{flink.version}.jar
+* flink-hadoop-compatibility_{scala_version}-{flink.version}.jar
+* flink-shaded-hadoop-2-uber-{hadoop.version}-{flink-shaded.version}.jar
+* hive-exec-2.x.jar (for Hive 1.x, you need to copy hive-exec-1.x.jar, hive-metastore-1.x.jar, libfb303-0.9.2.jar and libthrift-0.9.2.jar)
+
+Then you can use hive connector in scala shell like following:
+
+{% highlight scala %}
+Scala-Flink> import org.apache.flink.table.catalog.hive.HiveCatalog
+Scala-Flink> val hiveCatalog = new HiveCatalog("hive", "default", "<Replace it with HIVE_CONF_DIR>", "2.3.4");
+Scala-Flink> btenv.registerCatalog("hive", hiveCatalog)
+Scala-Flink> btenv.useCatalog("hive")
+Scala-Flink> btenv.listTables
+Scala-Flink> btenv.sqlQuery("<sql query>").toDataSet[Row].print()
+{% endhighlight %}
