I think we don't guarantee logs are in the same format between upgrades. The 
best effort is just adding more info in the logs so simple tools like counting 
Exceptions can still work. But that could still break tools that use regex 
patterns to match some long strings.

The HMS notification events are generated by HMS so they don't have Impala 
query ids. They might come from external systems like Hive or Spark. And 
currently there is no way for Impala to inject the query id when HMS generating 
the events.

BTW, if the event is generating by Impala statements, it will be ignored by 
self-event evaluation. Maybe not much info to log.

Done. Ideally we should just log the reason/goal to acquire the lock similar to 
how we log the reason for metadata loading. But there are too many call sites 
to change.

String.format() still uses different kinds of place holder for different data 
types. Just the Preconditions methods need the change.

It's still used in some places where we don't have the FeTable object, e.g. 
when checking the msTable from HMS:
