Xiao Chen updated HADOOP-13807:
---
Description:
The renewal thread should not be spawned if the keytab is external.
Because of HADOOP-13805 there can be a case that an UGI does not have a keytab
because authentication is managed by the host program. In such case we should
not spawn the renewal thread.
Currently this is logging a warning "Exception encountered while running the
renewal command. Aborting renew thread. " and exiting the thread. The warning
may be misleading and running the thread is not really needed.
