Subject [jira] [Created] (YARN-5305) Yarn Application log Aggreagation fails due to NM can not get correct HDFS delegation token III

Xianyin Xin created YARN-5305:
---------------------------------

             Summary: Yarn Application log Aggreagation fails due to NM can not get correct
HDFS delegation token III
                 Key: YARN-5305
                 URL: https://issues.apache.org/jira/browse/YARN-5305
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
            Reporter: Xianyin Xin


Different with YARN-5098 and YARN-5302, this problem happens when AM submits a startContainer
request with a new HDFS token (say, tokenB) which is not managed by YARN, so two tokens exist
in the credentials of the user on NM, one is tokenB, the other is the one renewed on RM (tokenA).
If tokenB is selected when connect to HDFS and tokenB expires, exception happens.
