[jira] [Created] (FLINK-2987) Flink 0.10 fails to start on YARN
2.6.0
Robert Metzger created FLINK-2987:
-------------------------------------
Summary: Flink 0.10 fails to start on YARN 2.6.0
Key: FLINK-2987
URL: https://issues.apache.org/jira/browse/FLINK-2987
Project: Flink
Issue Type: Bug
Components: Build System, YARN Client
Affects Versions: 0.10
Environment: Microsoft Azure HDInsight on Linux: 3.2.1000.0
Reporter: Robert Metzger
Assignee: Robert Metzger
Fix For: 0.10.1
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

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}}.
