Subject [jira] [Commented] (CASSANDRA-10992) Hanging streaming sessions
Date Sat, 14 May 2016 06:33:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15283451#comment-15283451

mlowicki commented on CASSANDRA-10992:
--------------------------------------

Upgrade to 2.1.14 didn't helped. Still even almost 12h after end of repair run (using Cassandra
Reaper) I've active streams (all with progress set to 100%). {{streaming_socket_timeout_in_ms}}
has default value (3600000).

> I've started recently running repair using [Cassandra Reaper|https://github.com/spotify/cassandra-reaper]
 (built-in {{nodetool repair}} doesn't work for me - CASSANDRA-9935). It behaves fine but
I've noticed hanging streaming sessions:

> Such sessions are left even when repair job is long time done (confirmed by checking
Reaper's and Cassandra's logs). {{streaming_socket_timeout_in_ms}} in cassandra.yaml is set
to default value (3600000).
