Adam Masters updated CASSANDRA-5892:
------------------------------------
Description:
When using CqlPagingRecordReader, specifying a custom where clause using
CqlConfigHelper.setInputWhereClauses() throws an exception when a GT (>)
comparator is used.
Exception:
java.lang.RuntimeException at
org.apache.cassandra.hadoop.cql3.CqlPagingRecordReader$RowIterator.executeQuery(CqlPagingRecordReader.java:646)
Caused by: InvalidRequestException(why:Invalid restrictions found on ts) at
org.apache.cassandra.thrift.Cassandra$prepare_cql3_query_result.read(Cassandra.java:39567)
This is due to the paging mechanism inserting a GT comparator on the same
composite key as the custom where clause, resulting in an invalid CQL
statement. For example ("ts > '634926385000000000'" being the custom where
clause):
SELECT * FROM "test_cf"
WHERE token("key") = token( ? ) AND "ts" > ?
AND ts > '634926385000000000' LIMIT 3 ALLOW FILTERING
