[jira] [Commented] (FLINK-11720) ES5: ElasticsearchSinkITCase failing

["Dawid Wysakowicz (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-11720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16774255#comment-16774255 ] 

Dawid Wysakowicz commented on FLINK-11720:
------------------------------------------

I've seen it somewhere before, can't say where though :(

This is unfortunately due to bug in ES on some OSs: https://github.com/elastic/elasticsearch/issues/23486
It was fixed in ES 5.3+, unfortunately we cannot upgrade our ES5 connector to any 5.2+ version (as far as I remember) as they broke some API that we depend on.
Not sure what we can do about this one.
