Subject [jira] [Commented] (IGNITE-5794) BinaryMetadata is lost if all server nodes have been restarted
Date Mon, 07 Aug 2017 07:50:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-5794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16116201#comment-16116201
] 

Sergey Chugunov commented on IGNITE-5794:
-----------------------------------------

More specific detail: after reconnect client still has binary metadata about custom type in
BinaryContext::descByClass collection.
So to fix the root cause problem descriptors for custom types must be cleaned up from it,
however it must be extensively tested to be sure that such a change won't break anything else.

>                 URL: https://issues.apache.org/jira/browse/IGNITE-5794
>             Project: Ignite
>          Issue Type: Bug
>          Components: binary, general
>    Affects Versions: 2.1
>            Reporter: Ilya Lantukh
>
> Steps to reproduce are described here: http://apache-ignite-users.70518.x6.nabble.com/Problem-with-Messages-after-client-reconnect-td15127.html#none
> This problem occurs because client has metadata in it's local metadata cache and decides
that server node should have it too. But server lost it after restart.
> Possible fixes:
> - Make client nodes re-send all contents of local metadata cache after reconnect.
> - If node doesn't have metadata to process incoming message, it should request it from
sender node.
