> HBase will retry 300+ times if an exception occurs on the server-side. To prevent this, implementors need to wrap any exceptions that occur with a DoNotRetryIOException
> This should be done for OmidSnapshotFilter, OmidCompactor, and OmidRegionScanner methods that implement HBase methods. For examples in Phoenix, see:
>  * BaseScannerRegionObserver.postScannerOpen()
>  * NonAggregateRegionScannerFactory.getTopNScanner() anonymous BaseRegionScanner implementation
