-----------------------------------
Summary: Make a symlink of
hadoop-yarn-server-timelineservice-hbase-coprocessor.jar to
hadoop-yarn-server-timelineservice-hbase-coprocessor-version.jar
Key: BIGTOP-3985
URL: https://issues.apache.org/jira/browse/BIGTOP-3985
Project: Bigtop
Issue Type: Improvement
Reporter: caijialiang
Attachments: image-2023-08-09-10-28-35-627.png
When using YARN Timeline Service v2, you need to configure the following
property in {{{}yarn-site{}}}:
{{yarn.timeline-service.hbase.coprocessor.jar.hdfs.location}}
{{hadoop-yarn-server-timelineservice-hbase-coprocessor-3.3.5.jar}}
This binding to version 3.3.5 can complicate automated configuration and
installation. Similar to other components that depend on ZooKeeper's jar,
symbolic links are often created to handle version dependencies, generating
{{{}zookeeper.jar{}}}. Both Ambari HDP and Bigtop stacks utilize similar code
for configuring this property, making it easier to automatically populate the
configuration without needing to consider the specific Hadoop version.

Therefore, I propose adding a symbolic link for
{{hadoop-yarn-server-timelineservice-hbase-coprocessor-3.3.5.jar}} to enhance
user configuration convenience and simplify Ambari's configuration process.
