@obrobecker ,   I was having the same issue in a similar environment. I did the following steps to fix it: - Rename /usr/hdp/current/hadoop-client/conf/embedded-yarn-ats-hbase/hbase-site.xml to hbase-site.xmlBkp - Copy /usr/hdp/current/hbase-client/conf/hbase-site.xml to /usr/hdp/current/hadoop-client/conf/embedded-yarn-ats-hbase - Execute the following commands: export HBASE_CLASSPATH_PREFIX=/usr/hdp/current/hadoop-yarn-client/timelineservice/*; /usr/hdp/current/hbase-client/bin/hbase org.apache.hadoop.yarn.server.timelineservice.storage.TimelineSchemaCreator -Dhbase.client.retries.number=35 -create -s - Using hbase shell, run the following commands: grant 'yarn', 'RWXCA' grant 'yarn-ats', 'RWXCA' Hope it helps.   Regards   Greg   ...
