LOGGED batching was introduced after reintroducing batch-by-replica. After switching back to UNLOGGED batching, and keeping batch-by-replica, I've run the same test 11 times (once after rebooting the machine) and I could not reproduce the issue any longer. Let's keep on monitoring on Jenkins though. > test_bulk_round_trip_blogposts is failing occasionally > ------------------------------------------------------ > > Key: CASSANDRA-10938 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10938 > Project: Cassandra > Issue Type: Sub-task > Components: Tools > Reporter: Stefania > Assignee: Stefania > Fix For: 2.1.x > > Attachments: 6452.png, node1_debug.log, node2_debug.log, node3_debug.log > > > We get timeouts occasionally that cause the number of records to be incorrect: > http://cassci.datastax.com/job/trunk_dtest/858/testReport/cqlsh_tests.cqlsh_copy_tests/CqlshCopyTest/test_bulk_round_trip_blogposts/ -- This message was sent by Atlassian JIRA (v6.3.4#6332)
