    One should be able to configure CDAP services to start at boot along with hadoop/hbase. Unfortunately the CDAP startup process is not flexible enough to tolerate when hadoop/hbase services may still be initiliazing. The first failure is the hive check fails due to HDFS not being out of safemode yet. (HDFS was 2 seconds away from leaving safemode). Another failure is the master startup checks do not tolerate when HBase is still initializing: {code} 2016-05-18 23:50:08,550 - ERROR [main:c.c.c.m.s.MasterStartupTool@97] - HBaseCheck failed: Unable to connect to HBase. Please check that HBase is running and that the correct HBase configuration (hbase-site.xml) and libraries are included in the CDAP master classpath. 2016-05-18 23:50:08,577 - ERROR [main:c.c.c.m.s.MasterStartupTool@99] - Root cause: RemoteWithExtrasException: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing at org.apache.hadoop.hbase.master.HMaster.checkInitialized( at org.apache.hadoop.hbase.master.MasterRpcServices.getTableDescriptors( at org.apache.hadoop.hbase.protobuf.generated.MasterProtos$MasterService$2.callBlockingMethod( at at at org.apache.hadoop.hbase.ipc.RpcExecutor.consumerLoop( at org.apache.hadoop.hbase.ipc.RpcExecutor$ at 2016-05-18 23:50:08,577 - ERROR [main:c.c.c.m.s.MasterStartupTool@102] - Errors detected while starting up master. Please check the logs, address all errors, then try again. {code}
