Thanks for the response. I lost access to my cluster over the weekend,
so I had to wait until today to check.
All of the correct Hive jars are in classpath.txt. Also, this error
seems to be happening in the driver rather than the executors. It's
running in yarn-client mode, so it should use the classpath of my local
JVM, which also contains the Hive jars. I also checked for that class
specifically and it is there. Does Spark do anything funny on the driver
side that would make the Hive classes on the classpath unavailable?

Do you have all your hive jars listed in the classpath.txt /
SPARK_DIST_CLASSPATH env., specifically the hive-exec jar? Is the
location of that jar also the same on all the distributed hosts?
Passing an explicit executor classpath string may also help overcome
this (replace HIVE_BASE_DIR to the root of your hive installation):
--conf "spark.executor.extraClassPath=$HIVE_BASE_DIR/hive/lib/*"

I'm trying to run a basic "Hello world" type example using DataFrames
with Hive in yarn-client mode. My code is:
JavaSparkContext sc = new JavaSparkContext("yarn-client", "Test app"))
HiveContext sqlContext = new HiveContext(sc.sc <http://sc.sc>());
sqlContext.sql("SELECT * FROM my_table").count();
The exception I get on the driver is:
java.lang.ClassNotFoundException:
org.apache.hadoop.hive.ql.plan.TableDesc
There are no exceptions on the executors.
That class is definitely on the classpath of the driver, and it runs
without errors in local mode. I haven't been able to find any similar
errors on google. Does anyone know what I'm doing wrong?
