Change subject: IMPALA-3820: Handle linkage errors while loading Java UDFs in Catalog ...................................................................... IMPALA-3820: Handle linkage errors while loading Java UDFs in Catalog Currently Catalog aborts at startup if the class loader loading Java UDFs throws a LinkageError (e.g., NoClassDefError). The code has been designed to catch a generic "Exception" and ignore any incompatible or erroneous UDFs but it can't handle any "Error"s. Java generally doesn't encourage to handle all types of "Error"s, however given the Catalog tries to load thirdparty udfs, it is possible that there might be missing dependencies that the Catalog is expected to handle. Testing: I confirmed the fix with manual testing. Created a sample udf with multiple class dependencies and created a sample function in Hive. Then I corrupted the jar by removing some classes classes from it. Impala catches the expected exception added in this patch instead of aborting at startup.
