It happens due to DelegationKey_45 file, which has size 0. You can easily reproduce it by
placing this file under /var/user/cluster/yarn/rm/system/FSRMStateRoot/RMDTSecretManagerRoot/
direcrory in hdfs and then restart RM.


The solution is to add check for empty stream with DelegationKey data to prevent RM failing
during start.
Additionally, there is method "storeRMDTMasterKeyState" in ZKRMStateStore.java that stores
DelagationKey file (file was broken (empty) in our case). This method can leave DelegationKey
file empty in case of errors in write method of DataOutputStream . There is already fixed
jira that prevents possible resource leak in this method: https://issues.apache.org/jira/browse/YARN-5663
