------------------------------------------
Summary: RetriesExhaustedWithDetailsException can create a
pathological feedback loop with multigets
Key: HBASE-29265
URL: https://issues.apache.org/jira/browse/HBASE-29265
Project: HBase
Issue Type: Improvement
Reporter: Hernan Gelaf-Romer
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.
