-------------------------------------------------------
Summary: java.lang.AssertionError when running select queries
Key: CASSANDRA-8461
URL: https://issues.apache.org/jira/browse/CASSANDRA-8461
Project: Cassandra
Issue Type: Bug
Components: API
Environment: ubuntu 14.04
Reporter: Chamila Dilshan Wijayarathna
I have a column family with following schema.
CREATE TABLE corpus.trigram_category_ordered_frequency (
id bigint,
word1 varchar,
word2 varchar,
word3 varchar,
category varchar,
frequency int,
PRIMARY KEY(category,frequency,word1,word2,word3)
);
When I run
select word1,word2,word3 from corpus.trigram_category_ordered_frequency where
category IN ('N','A','C','S','G') order by frequency DESC LIMIT 10;
I am getting error saying
<ErrorMessage code=0000 [Server error] message="java.lang.AssertionError">
But when I ran
select * from corpus.trigram_category_ordered_frequency where category IN
('N','A','C','S','G') order by frequency DESC LIMIT 10;
it works without any error.
system log for this error is as follows.
ERROR [SharedPool-Worker-1] 2014-12-11 20:42:20,152 Message.java:538 -
