---------------------------------------

             Summary: [Atsv2] TimelineSchemaCreator fails to create flowrun table causes RegionServer down!
                 Key: YARN-7212
                 URL: https://issues.apache.org/jira/browse/YARN-7212
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Rohith Sharma K S


*Hbase-2.0* officially support *hadoop-alpha* compilations. So I was trying to build and test with HBase-2.0. But table schema creation fails and causes RegionServer to shutdown with following error
{noformat}
Caused by: java.lang.NoSuchMethodError: org.apache.hadoop.hbase.Tag.asList([BII)Ljava/util/List;

Since HBase-2.0 community is ready to release Hadoop-3.x compatible versions, ATSv2 also need to support HBase-2.0 versions. For this, we need to take up a task of test and validate HBase-2.0 issues!
