Andrey Konstantinov updated CASSANDRA-12149:
--------------------------------------------
Description:
If I execute the sequence of queries (see the attached file), Cassandra aborts
a connection reporting NPE on server side. SELECT query without token range
filter works, but does not work when token range filter is specified. My intent
was to issue multiple SELECT queries targeting the same single partition,
filtered by a column indexed by SASI, partitioning results by different token
ranges.
Output from cqlsh on SELECT is the following:
cqlsh> SELECT namespace, entity, timestamp, feature1, feature2 FROM
mykeyspace.myrecordtable WHERE namespace = 'ns2' AND entity = 'entity2' AND
feature1 > 11 AND feature1 < 31 AND token(namespace, entity) <=
9223372036854775807;
ServerError: <ErrorMessage code=0000 [Server error]
message="java.lang.NullPointerException">
