> Customer started a few Impala Virtual Warehouses that all connected to the same Database Catalog in DW. After it finished starting, they noticed tables seen in their Hive VW were missing from their Impala VW. Looking in Catalog pod logs we Event Processor was stuck in Error state:
> {quote}W0528 07:11:42.398236 228 MetastoreEventsProcessor.java:844] Event processing is skipped since status is ERROR. Last synced event id is 33348458
