Subject [jira] [Commented] (CASSANDRA-4115) UNREACHABLE schema after decommissioning a non-seed node
Date Fri, 06 Apr 2012 21:36:16 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248890#comment-13248890
] 

Tyler Patterson commented on CASSANDRA-4115:
--------------------------------------------

After testing a little more I found the following:

On 1.0.9 I get the following schema when sleeping 30 seconds after the decommission:
{'00000000-0000-1000-0000-000000000000': ['127.0.0.1'],
 'UNREACHABLE': ['127.0.0.2']}

On 1.1, this is the schema 30 seconds after the decommission:
{'59adb24e-f3cd-3e02-97f0-5b395827453f': ['127.0.0.1'],
 'UNREACHABLE': ['127.0.0.2']}

If I increase the sleep after decommissioning from 30 to 90 seconds, then 1.0.9 now returns
only one schema, while 1.1 still fails with the UNREACHABLE schema. 

None of these tests were done with the recent patch.

UNREACHABLE is listed:
