Guanghao Zhang commented on HBASE-18569:
----------------------------------------
bq. if (info == null || info.isOffline() || info.isSplitParent() ||
loc.getServerName() == null)
Here add a info.isOffline() case, but don't see this condition in onScanNext
method?
bq. if (LOG.isDebugEnabled())
Whe removed LOG.isTraceEnabled and keep LOG.isDebugEnabled()?
bq. Thread.sleep(1000);
Is this enough for virtual machine which run the unit test? It may be flaky if
the unit test run slow?
> Add prefetch support for async region locator
