> tserver crashes on Scan when [lowerPrimaryKey, upperPrimary) and predicates of primary column do not overlap.
> Example of table in TestScannerMultiTablet unittest, The table like this:
> {code:java}
> key1 (string) | key2 (string) | value (string){code}
> The data layout ends up like this:
> {code:java}
> tablet '', '1': no rows
> tablet '1', '2': '111', '122', '133'
> tablet '2', '3': '211', '222', '233'
> tablet '3', '': '311', '322', '333'{code}
> add Scan PrimaryKeyBounds: ['12', '13')
> add Scan Predicate: key2 <= '1'
> Run the example, ts will crash, and print "NONE predicate can not be pushed into key"
