Description

While testing Flink for the release, I noticed that it does not start on YARN due to classloading issues.

The error message is the following

robert@hn0-apache:~/flink-0.10.0$ ./bin/yarn-session.sh  -n 2

The issue occurs with the following versions:

• flink-0.10.0-bin-hadoop26-scala_2.11.tgz
• flink-0.10.0-bin-hadoop26-scala_2.10.tgz
• flink-0.10.0-bin-hadoop27-scala_2.10.tgz

It works for:

• flink-0.10.0-bin-hadoop24-scala_2.10.tgz
• flink-0.9.1-bin-hadoop26.tgz

Interestingly, the issue only occurs, when HADOOP_CONF_DIR is set. Otherwise, the YARN client is starting until its unable to connect to the RM.

The missing class is in the jersey-client dependency, which we exclude from Hadoop, in flink-shaded-hadoop2.
