Rajeshbabu Chintaguntla commented on PHOENIX-2903:
--------------------------------------------------
No..region.startRegionOperation() acquire read lock so there won't be any split
till the scanners created. We are not scanning any record to identify the
split here.
I hope we are discussing with respect to these lines only(if something else pls
forgive me I have missed that part)
{noformat}
+ // Check again while we have the region lock as it's
possible
+ // we've split after the check we did in preScannerOpen()
+ throwIfScanOutOfRegion(scan,
c.getEnvironment().getRegion());
{noformat}
> Handle split during scan for row key ordered aggregations
