Bharath Vissapragada has uploaded a new patch set (#5). 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: Added an e-e test that loads a corrupt Java UDF from Hive and restarts Catalog to make sure its up and the function count tallies.
