Jonathan Lawlor commented on HBASE-13193:
-----------------------------------------

Ran the failing test (TestSplitTransactionOnCluster) three times locally with 
the patch applied to branch-1 and all test runs passed. Failure seems unrelated.

> RegionScannerImpl filters should not be reset if a partial Result is returned

> In RegionScannerImpl the filters get reset during calls to nextRaw:
> {code}
> public NextState nextRaw(List<Cell> outResults, int batchLimit, long 
> remainingResultSize)
>         throws IOException {
>   ...
>   resetFilters();
>   if (isFilterDoneInternal()) {
>   ...
> }
> {code}
> This creates a problem when returning partial Results because filters should 
> only be reset in between rows (i.e. after all of the cells for a particular 
> row have been returned). If a partial Result is returned, there are still 
> cells in the row that have not been evaluated yet and we should avoid 
> resetting the filter since it will wipe away all state information for that 
> filter.
