--------------------------------
Summary: Use INTERNAL_HADOOP_CLASSPATHS as classpath for launching
Yarn cluster for Scala Shell
Key: FLINK-9086
URL: https://issues.apache.org/jira/browse/FLINK-9086
Project: Flink
Issue Type: Improvement
Components: Startup Shell Scripts
Affects Versions: 1.4.0
Reporter: Keda Ruan
Some environment does not have hadoop jars in {{HADOOP_CLASSPATH}}, causing
Flink Yarn cluster unable to start due to some jars missing. For example Flink
1.4.0 drops jersey dependency in its shaded hadoop jar, causing Yarn cluster
unable to start:

at java.lang.ClassLoader.defineClass(ClassLoader.java:763)
{quote}
Since there is a {{INTERNAL_HADOOP_CLASSPATHS}} in {{config.sh}} that has
{{hadoop classpath}} result, we can utilize this and improve the user
experience on starting Flink Yarn cluster for Scala Shell.
