> HadoopAccessorService sets the renewer as "oozie mr token" for the delegation
> tokens instead of the JT or RM service principal name. Because of this long
> running jobs fail if the token lifetime is not set to 7 days (some value > 2
> days) by JT. JT (Hadoop 1.0.2) did not have support for renewing and
> cancelling tokens to itself and so it did not matter what the renewer was set
> to. But that support is being added in RM in Hadoop 0.23/2.0.0 in YARN-50 as
> it would lead to RM going OOM as it runs with lot less memory than JT.
