Subject [jira] [Commented] (CASSANDRA-11983) Migration task failed to complete
Date Sat, 18 Jun 2016 20:13:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15338151#comment-15338151

Chris Love commented on CASSANDRA-11983:
----------------------------------------

I understand what you are saying, and I agree that removing the code is not a fix.  

The new nodes were getting stuck in a loop starting. Above 30 nodes it start to take 10 min
plus to lanch a node. That is not acceptable. What is the node doing? I don't understand why
it is taking so long.

As I mentioned in a perfect world I would disable autoboostrap, but the config needs to be
immutable.

What are the nodes doing? How can we speed up what they are doing. To me this doesn't seem
to be a good approach.

> The errors increase as more nodes are added to the ring, as I am creating a ring of 1k
nodes.
