> Reporter: Hernan Gelaf-Romer
> Assignee: Hernan Gelaf-Romer
> Priority: Major

> In HBase 2.X, meta cache clear exceptions can potentially be obfuscated,
> making it hard to understand why we're clearing the meta cache. We should

> # Avoid using "UnknownException" as the exception type in the meta cache
> clear metric if the exception is known at runtime
