Subject [jira] [Commented] (SOLR-13285) ByteArrayUtf8CharSequence cannot be cast to java.lang.String exception during replication
Date Tue, 11 Jun 2019 22:23:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-13285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16861556#comment-16861556
] 

Jan Høydahl commented on SOLR-13285:
------------------------------------

SOLR-13331 is indeed fixed and released in 7.7.2 by Jason. But someone have continued the
discussion on that same JIRA about fixing more related stuff. However that needs to go in
a new JIRA.

> Since upgrading to 7.7 (also tried 7.7.1, and 8.1.0) from 6.6.4, we're seeing the following
errors in the SolrCloud elected master for a given collection when updates are written.  This
was after a full reindex of data (fresh build).

> I noticed there some similar issues raised in 7x (https://issues.apache.org/jira/browse/SOLR-13255),
so I don't know if this is the same sort of thing?
> I've tried solr-users mailing list, and stackoverflow but to no avail. Please let me
know if there is any other information I can provide.
