Subject [jira] [Commented] (CASSANDRA-9267) Bootstrapping node, nodetool netstats shows all files 100% received immediately
Date Thu, 30 Apr 2015 22:33:06 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522398#comment-14522398

Brandon Williams commented on CASSANDRA-9267:
---------------------------------------------

First I'd see if this reproduces on 2.0.14 so you aren't wasting your time.  Then I'd look
at the appropriate calls in the nodetool source itself (all the Node* files in o.a.c.tools)
and then StreamManager.java since it's just passing the raw info to nodetool.

> Using Cassandra v.2.0.10.
> Following the progress of a new node bootstrapping with 'nodetool netstats' I notice
that each file is shown as 100% received immediately.

> $ nodetool netstats -h 172.16.11.17

> The node is bootstrapping 200GB in total, and quite quickly/painlessly as far as I can
tell, but each file is shown as 100% transferred already.
> Since this is fairly minor I'm happy to hunt it down and patch it myself if desirable.
Any pointers where to start appreciated.
