> 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
