Subject [jira] [Updated] (CASSANDRA-13170) dtest failure in compaction_test.TestCompaction_with_LeveledCompactionStrategy.compaction_throughput_test
Date Thu, 02 Feb 2017 20:21:51 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-13170?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aleksandr Sorokoumov updated CASSANDRA-13170:
---------------------------------------------
    Status: Patch Available  (was: Open)

https://github.com/riptano/cassandra-dtest/pull/1434

The reason for the test to fail is that 5mb threshold is compared against the first matched
avgthroughput without unit conversion. In the node_debug.log attached, the threshold was compared
against 6.175KiB/s
