    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(HMaster.java:2303) at org.apache.hadoop.hbase.master.MasterRpcServices.getTableDescriptors(MasterRpcServices.java:866) at org.apache.hadoop.hbase.protobuf.generated.MasterProtos$MasterService$2.callBlockingMethod(MasterProtos.java:55648) at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2170) at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:109) at org.apache.hadoop.hbase.ipc.RpcExecutor.consumerLoop(RpcExecutor.java:133) at org.apache.hadoop.hbase.ipc.RpcExecutor$1.run(RpcExecutor.java:108) at java.lang.Thread.run(Thread.java:745) 2016-05-18 23:50:08,577 - ERROR [main:c.c.c.m.s.MasterStartupTool@102] - Errors detected while starting up master.
