-----------------------------------
Summary: Wrong FS while starting YARN session without correct HADOOP_HOME
Key: FLINK-1914
URL:
https://issues.apache.org/jira/browse/FLINK-1914 Project: Flink
Issue Type: Bug
Components: YARN Client
Reporter: Zoltán Zvara
Priority: Trivial
When YARN session invoked ({{yarn-session.sh}}) without a correct {{HADOOP_HOME}} (AM still deployed to - for example to {{0.0.0.0:8032}}), but the deployed AM fails with an {{IllegalArgumentException}}:

{code}
IMO this {{IllegalArgumentException}} should get handled in {{org.apache.flink.yarn.Utils.registerLocalResource}} or on an upper level to provide a better error message. This needs to be looked up from YARN logs at the moment, which is painful to a trivial mistake like missing {{HADOOP_HOME}}.
