Dan Burkert updated KUDU-1652:
------------------------------
Description: Both the Java client and C++ client/server currently have a
bug where attempting a scan with an {{IS NOT NULL}} predicate on a primary key
column can throw an exception (Java), or crash the C++ client or server. This
is a rare situation currently since {{IS NOT NULL}} is not publicly accessible,
so it has to come from a simplified predicate like {{my_int8_column <= 127}}.
The fix is straightforward: stop encoding the lower/upper bound keys when an
{{IS NOT NULL}} predicate is encountered. (was: Both the Java client and C++
