Hi @Daniel Zafar,
Can you please navigate to the host where Timeline Reader is installed and Install Hbase Client in that host and let me know the result.
Seeing the code base(the missing file is in hadoop-yarn-server-timelineservice-hbase-client) I have strong feeling this can fix the issue.
Code reference : https://github.com/hortonworks/hadoop-release/blob/HDP-18.104.22.168-1634-tag/hadoop-yarn-project/hadoop-y...
Please log in and accept the answer if you find it helpful :)
