Subject [jira] [Updated] (CASSANDRA-12149) NullPointerException on SELECT with SASI index
Date Fri, 08 Jul 2016 04:10:11 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-12149?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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">
