Subject [jira] [Commented] (CASSANDRA-11195) static_columns_paging_test upgrade dtest flapping
Date Thu, 17 Mar 2016 20:46:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15200341#comment-15200341
] 

Russ Hatch commented on CASSANDRA-11195:
----------------------------------------

this is starting to look more like a paging bug (driver or c*) to me. If I attach a python
debugger to the test, I can continue to query with page size 2, and only get partial results.
if I open up a cqlsh session I can see all the rows in fact exist.

> The failures indicate there is missing data. I have not reproduced the failure locally.
I've only seen the failures on 2-node clusters with RF=1, not on the 3-node runs with RF=3.
