Taras Bobrovytsky has uploaded a new patch set (#2). Change subject: IMPALA-5259: Add REFRESH FUNCTIONS <db> statement ......................................................................
IMPALA-5259: Add REFRESH FUNCTIONS <db> statement Before this patch, Impala relied on INVALIDATE METADATA to load externally added UDFs from HMS. The problem with this approach is that INVALIDATE METADATA affects all databases and tables in the entire cluster. In this patch, we add a REFRESH FUNCTIONS <db> statement that reloads the functions of a database from HMS. We return a list of updated and removed db functions to the issuing Impalad in order to update its local catalog cache. Testing: - Ran a private build which passed.
