Hi, I recently experienced versioning clashes with the okio and okhttp when trying to deploy a Flink 1.6.0 app to AWS EMR on Hadoop 2.8.4. After investigating and talking to the okio team (see this issue) <https://github.com/square/okio/issues/559>, I found that both okio and okhttp exist in the Flink uber jar with versions 1.4.0 and 2.4.0, respectively, whereas I'm including versions 2.2.2 and 3.13.1 in my shaded jar. The okio team suggested that Flink should shade the uber jar to fix the issue, but I'm wondering if there is something I can do on my end to have all versions exist simultaneously.
>From the issue, here are the okio contents of the uber jar: *jar -tf flink-shaded-hadoop2-uber-1.6.0.jar | grep okio* META-INF/maven/com.squareup.okio/ META-INF/maven/com.squareup.okio/okio/ META-INF/maven/com.squareup.okio/okio/pom.properties META-INF/maven/com.squareup.okio/okio/pom.xml okio/ okio/AsyncTimeout$1.class okio/AsyncTimeout$2.class okio/AsyncTimeout$Watchdog.class okio/AsyncTimeout.class okio/Base64.class okio/Buffer$1.class okio/Buffer$2.class okio/Buffer.class okio/BufferedSink.class okio/BufferedSource.class okio/ByteString.class okio/DeflaterSink.class okio/ForwardingSink.class okio/ForwardingSource.class okio/ForwardingTimeout.class okio/GzipSink.class okio/GzipSource.class okio/InflaterSource.class okio/Okio$1.class okio/Okio$2.class okio/Okio$3.class okio/Okio.class okio/RealBufferedSink$1.class okio/RealBufferedSink.class okio/RealBufferedSource$1.class okio/RealBufferedSource.class okio/Segment.class okio/SegmentPool.class okio/SegmentedByteString.class okio/Sink.class okio/Source.class okio/Timeout$1.class okio/Timeout.class okio/Util.class Thank you, Austin Cawley-Edwards
