Subject [jira] [Commented] (CASSANDRA-4880) Endless loop flushing+compacting system/schema_keyspaces and system/schema_columnfamilies
Date Thu, 08 Nov 2012 18:10:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13493355#comment-13493355
] 

Mike Heffner commented on CASSANDRA-4880:
-----------------------------------------

We also see this after upgrading a node from 1.1.0 -> 1.1.6 in our ring. We also saw increased
flush writes begin continuously on the other 1.1.0 nodes in the ring after the 1.1.6 was started,
but not as rapidly as on the 1.1.6 node. There were also periodic HintedHandoffs occurring
around the ring after the 1.1.6 node came up.
