Xu Yao updated KUDU-2447:
-------------------------
Description:
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"
