Running community 5.2.0 and attempted to update to MEP 3.0.0 and apparently messed something up. My 3 HBase masters will not start - they are also Zookeepers, which thankfully is fine. A look at the log shows that it thinks the port (16000) is already in use:
2017-06-12 14:02:26,770 INFO [main] regionserver.RSRpcServices: master/hd15.sec.bnl.local/192.168.4.15:16000 server-side HConnection retries=350
2017-06-12 14:02:26,934 INFO [main] ipc.SimpleRpcScheduler: Using deadline as user call queue, count=3

java.lang.RuntimeException: Failed construction of Master: class org.apache.hadoop.hbase.master.HMaster
Caused by: java.net.BindException: Address already in use
netstat -tulpn shows nothing on that port.
Even the same after a reboot.
I get an error when trying to start it with maprcli:
[root@hd15:/opt/mapr/hbase/hbase-1.1.8/logs]# maprcli node services -hbmaster start -nodes 192.168.4.15
Unable to find mlockall_agent, hbase must be compiled with -Pnative
