Subject [jira] [Commented] (CASSANDRA-13712) DropTable could cause hints
Date Tue, 22 Aug 2017 14:53:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16136889#comment-16136889
] 

Aleksey Yeschenko commented on CASSANDRA-13712:
-----------------------------------------------

Schema propagation is not instantaneous, and even it were, there'd still possibly be encoded
hints in the write buffers. This is not an issue, because they'll be safely skipped on replay.

> While dropping table and there's on going write traffic, we saw hints generated on each
node. You can find hints dispatch message in the log. Not sure if it's an issue.
> Here are the reproduce steps:
> 1. Create a 3 nodes cluster:
>   {{$ ccm create test13696 -v 3.0.14 && ccm populate -n 3 && ccm start}}
> 2. Send some traffics with cassandra-stress (blogpost.yaml is only in trunk, if you use
another yaml file, change the RF=3)
>   {{$ tools/bin/cassandra-stress user profile=test/resources/blogpost.yaml cl=QUORUM
truncate=never ops\(insert=1\) duration=30m -rate threads=2 -mode native cql3 -node 127.0.0.1}}
> 3. While the traffic is running, drop table
>   {{$ cqlsh -e "drop table  stresscql.blogposts"}}
