Description

(Re-opening from internal ticket)

authentication.cc is setting renewable life and then sleeping for approximately that amount of time and then kinit-ing again. It would be better to set the lifetime of tickets using -l option instead of renewable life. This would guard against failures in configuring renewable life. Note that since impala is kiniting in a loop, it doesn't really need renewable tickets.
