[jira] [Updated] (HDFS-2800) HA:
TestStandbyCheckpoints.testCheckpointCancellation is racy
[ https://issues.apache.org/jira/browse/HDFS-2800?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Todd Lipcon updated HDFS-2800:
------------------------------
Attachment: hdfs-2800.txt
Take two.
I moved the cancellation "context" to be a standalone class instead of being part of SaveNamespaceContext. It can then be passed in from the StandbyCheckpointer thread, which eliminates the race mentioned in one of the TODO comments.
I looped this test for quite some time and wasn't able to get it to fail, with this patch applied.
