Sylvain Lebresne commented on CASSANDRA-11016: ---------------------------------------------- I'll note that the truncate failures in the upgrade test are pretty easy to fix, see https://github.com/riptano/cassandra-dtest/pull/749 (I haven't checked this fix it tbh honest, but it's almost surely the problem). Haven't looked at the failure of replace_first_boot_test but from the error message that looks like a similar problem (the test not ensure a restart node has been detected by other ones when it should). > Fix flapping dtests with "unavailable" and "cannot achieve consistency" errors > ------------------------------------------------------------------------------ > > Key: CASSANDRA-11016 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11016 > Project: Cassandra > Issue Type: Bug > Reporter: Jim Witschey > > A number of dtests flap when they run a query and get an unavailable > exception or can't meet a particular CL. Examples include: > http://cassci.datastax.com/job/cassandra-2.2_dtest/470/testReport/replace_address_test/TestReplaceAddress/replace_first_boot_test/ > http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest/488/testReport/upgrade_tests.cql_tests/TestCQLNodes3RF3/range_tombstones_test/ > This seems to be a different issue than CASSANDRA-10730 -- bumping instance > sizes to m3.2xl stopped that class of error, but bumping instance sizes to > i2.4xl did not stop the errors described here. > I'm probably the best person to tackle this, but won't get to it for a bit, > so [~philipthompson] might take it if he has time sooner. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
