Szilard Nemeth updated YARN-5305:
---------------------------------
Summary: Yarn Application log Aggregation fails due to NM can not get
correct HDFS delegation token III (was: Yarn Application log Aggreagation
fails due to NM can not get correct HDFS delegation token III)
> Yarn Application log Aggregation 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
> Priority: Major
>
> 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.
> Supplementary: this problem happen due to that AM didn't use the service name
> as the token alias in credentials, so two tokens for the same service can
> co-exist in one credentials. TokenSelector can only select the first matched
> token, it doesn't care if the token is valid or not.
