Change subject: IMPALA-11528: Catalogd should start up even with a corrupt Hive function. ...................................................................... IMPALA-11528: Catalogd should start up even with a corrupt Hive function. This commit handles the case for a specific kind of corrupt function within the Hive Metastore in the following situation: A valid Hive SQL function gets created in HMS. This UDF is written in Java and must derive from the "UDF" class. After creating this function in Impala, we then replace the underlying jar file with a class that does NOT derive from the "UDF" class. In this scenario, catalogd should reject the function and still start up gracefully. Before this commit, catalogd wasn't coming up. The reason for this was because the Hive function FunctionUtils.getUDFClassType() has a dependency on UDAF and was throwing a LinkageError exception. To fix this, we need to include UDAF in the shaded jar.
