Roger Hernandez created CASSANDRA-7192:
------------------------------------------
Summary: QueryTrace for a paginated query exists only for the
first element of the list returned by getAllExecutionInfo()
Key: CASSANDRA-7192
URL: https://issues.apache.org/jira/browse/CASSANDRA-7192
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: A Cassandra 2.0.6 cluster of 16 nodes running on Ubuntu
12.04.2 LTS, using the Java Driver in the client.
Reporter: Roger Hernandez
Priority: Minor
Within the Java Driver, with tracing enabled, I execute a large query that
benefits from automatic pagination (with fetchSize=10).
I make sure to go through all of the ResultSet, and by the end of the query I
call getAllExecutionInfo() on the ResultSet. This returns an ArrayList of 9
ExecutionInfo elements (the number of pages it requested from Cassandra).
When accessing the QueryTrace in the ExecutionInfo from the ArrayList at index
0, I can retrieve the information without issues. However, the first is the
only one that has QueryTrace information, every other ExecutionInfo of the
array returns a NULL QueryTrace object.
