---------------------------------------

             Summary: Fix Elasticsearch version interference
                 Key: FLINK-7133
                 URL: https://issues.apache.org/jira/browse/FLINK-7133
             Project: Flink
          Issue Type: Bug
          Components: Streaming Connectors
    Affects Versions: 1.3.1, 1.3.0
            Reporter: Aljoscha Krettek
            Priority: Blocker
             Fix For: 1.3.2


At least two users have encountered problems with shading in the Elasticsearch connector:
 - https://lists.apache.org/thread.html/b5bc1f690dc894ea9a8b69e82c89eb89ba6dfc2fec2588d2ccacee2c@%3Cuser.flink.apache.org%3E
 - https://lists.apache.org/thread.html/2356670d168f61c20e34611e3c4aeb9c9b3f959f23a9833f631da1ba@%3Cuser.flink.apache.org%3E

The problem seems to be (quote from the second mail):

{code}
I've found out the source of the problem when I build flink locally.
elastic-search base depends on (by default) ES version 1.7.1 that depends on
asm 4.1 and that version is shaded to elasticsearch-base-jar. I tried to set
elasticsearch.version property in Maven to 5.1.2 (the same as elasticsearch5
connector) but then elasticsearch-base does not compile:

[ERROR] Failed to execute goal

{code}

To me, it seems like we have to get rid of the "base" package and have two completely separate packages.
