James Taylor commented on PHOENIX-1296:
---------------------------------------
Let's start with the easy fix for this one as I mentioned above: in the
UngroupedAggregateRegionObserver, in your if statement that detects an analyze
is being done, just always set the scan start/stop row to
HConstant.EMPTY_START_ROW and HConstant.EMPTY_END_ROW.
Then, for PHOENIX-1263, see my comment there.
> Scan entire region when tenant-specific table is analyzed

> Based on the issue you've uncovered (that stats must be updated completely
> for a region), there's a bit of follow on work needed if an ANALYZE is done
> on a tenant-specific table. This case will be optimized to only scan and
> analyze the current tenant's data, however we have to make sure that the
> entire region(s) containing that tenant's data is scanned (or we'll end up
> replacing the stats for that region with just the one we calculated for that
> tenant).
> We should be able to do that based on ScanUtil.isAnalyzeTable(scan) being
> true in DefaultParallelIteratorRegionSplitter and/or ParallelIterators.
