> -------------------------------------------------------------------------------
>
> Key: SPARK-23776
> URL: https://issues.apache.org/jira/browse/SPARK-23776
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 2.3.0
> Reporter: Bruce Robbins
> Priority: Minor
>
> This is a follow up to SPARK-23417.
> The pyspark-streaming tests print useful build instructions when certain
> components are missing in the build.
> pyspark-sql's udf and readwrite tests also have specific build requirements:
> the build must compile test scala files, and the build must also create the
> Hive assembly. When those class or jar files are not created, the tests throw
> only partially helpful exceptions, e.g.:
> {noformat}
> AnalysisException: u'Can not load class
> test.org.apache.spark.sql.JavaStringLength, please make sure it is on the
> classpath;'
> {noformat}
> or
> {noformat}
> IllegalArgumentException: u"Error while instantiating
> 'org.apache.spark.sql.hive.HiveExternalCatalog':"
> {noformat}
> You end up in this situation when you follow Spark's build instructions and
> then attempt to run the pyspark tests.
> It would be nice if pyspark-sql tests provide helpful build instructions in
> these cases.
