Environment is Hadoop 2.3.0, CDH 5.0, RM and NN in HA, Kerberos Security Rolling reboot of cluster was done. Services on each node was not stopped before, the machines were just shut down, rebooted and services started on each after reboot. Nodes were shut down in rolling manner such that one RM, NN etc. were available at all times.
After restart, all services came up but node managers failed to connect to Resource managers with "invalid Yarn Credentials". Kerberos keytabs etc. are valid. The Resource managers services had to be restarted again for node managers to connect successfully. Thoughts? Thanks,
