--------------------------------------------
I'm actually not convinced this is a problem. I don't actually think it's
possible for RetriesExhaustedWithDetailsException to clear the meta cache
> RetriesExhaustedWithDetailsException can create a pathological feedback loop
> with multigets

> URL: https://issues.apache.org/jira/browse/HBASE-29265
> Project: HBase
> Issue Type: Improvement
> Reporter: Hernan Gelaf-Romer
> Assignee: Hernan Gelaf-Romer
> Priority: Major
>
> Similar to https://issues.apache.org/jira/browse/HBASE-27487
>
> RetriesExhaustedWithDetailsException currently obscures that the underlying
> exception(s) may be OperationTimeoutExceededException. Because of this, we
> can still run into situations where slow request can trigger a flood of meta
> cache clearing exceptions, and hotspot the meta table.
>
> We should update our exception handling logic to special case these
> exceptions, and explicitly check to see if the underlying root cause for the
> request failures was due to an operation timeout.
