> 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
> {quote}
> Running "invalidate metadata \{table}" or global invalidate metadata shows
> the tables.
>
> Looking at old Catalog pod logs when the error first appeared shows this
> unique stacktrace that led to the ERROR state
