Subject kerberos ticket renewal for hadoop services
Date Sun, 29 Jun 2014 23:50:19 GMT
how do long lived services such as the namenode or yarn resourcemanager
deal with kerberos ticket expiration for the user that runs the service?

do they periodically renew/refresh their tickets by calling
SecurityUtil.login(conf, keytab, user, host)?

where can i find an example the code that handles this (in NameNode.java
its easy to find the initial login but i cannot find the code that handles
with expiration/renewal/refresh of tickets)?

thanks! koert
