[jira] [Commented] (CASSANDRA-11198) Materialized view
inconsistency
[ https://issues.apache.org/jira/browse/CASSANDRA-11198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15154884#comment-15154884 ]

--------------------------------------------

(from CASSANDRA-10910)
I cannot reproduce it from console.
I'm using the cluster through the Datastax Java Driver, the "TRACING ON;" is the rs.getExecutionInfo() or something else?
{quote}
In cqlsh (which it looks like you are using for the output you are generating), you can just use that line to start tracing and execute the {{SELECT}} query again.
If not, you can use [the driver with {{.enableTracing()}} and {{.getExecutionInfo()}}|http://docs.datastax.com/en/developer/java-driver/2.1/java-driver/tracing_t.html].
