Docker build in examples failing with error

[krishnaarava]

When I try to build an docker image in examples folder throws me an error.

docker build -t "onemoretest:1.0" .

Step 19/25 : RUN set -ex; wget -nv -O flink.tgz "$FLINK_TGZ_URL"; tar -xf flink.tgz --strip-components=1; rm flink.tgz; cp ./opt/flink-s3-fs-presto-1.8.1.jar ./lib/; cp ./opt/flink-s3-fs-hadoop-1.8.1.jar ./lib/; chown -R flink:flink .;

Looks like the path if no more available https://mirrors.ocf.berkeley.edu/apache/flink/flink-1.8.1/

Looks like 1.8.1 is no longer available. Only 1.8.2 is present. Let me submit a PR
