Looks like this was a breaking change introduced in Hadoop 2.7.0: In https://hadoop.apache.org/docs/r2.6.5/api/org/apache/hadoop/yarn/conf/YarnConfiguration.html we have:
static long DELEGATION_TOKEN_MAX_LIFETIME_DEFAULT static String DELEGATION_TOKEN_MAX_LIFETIME_KEY But in https://hadoop.apache.org/docs/r2.7.0/api/org/apache/hadoop/yarn/conf/YarnConfiguration.html we have: static long RM_DELEGATION_TOKEN_MAX_LIFETIME_DEFAULT static String RM_DELEGATION_TOKEN_MAX_LIFETIME_KEY Ram On Wed, Mar 22, 2017 at 11:59 PM, Chinmay Kolhatkar <[email protected]> wrote: > Hi All, > > I want to clarify whether my understanding is correct here. > > 1.
