Shen Yinjie commented on FLINK-14360: ------------------------------------- Yes, it is about Flink on Yarn deployment,similar to Spark on Yarn. In the current implementation,flink upload certain files to Hdfs according to client's fs.defaultFs, in the multi-cluster scenario, target Yarn cluster may not have tokens for this Hdfs. Thus, we need a flexible config option to let user pick necessary hdfs schemes. > Flink on yarn should support obtain delegation tokens of multi hdfs namespaces > ------------------------------------------------------------------------------ > > Key: FLINK-14360 > URL: https://issues.apache.org/jira/browse/FLINK-14360 > Project: Flink > Issue Type: Improvement > Components: Deployment / YARN > Reporter: Shen Yinjie > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > There's a scenario when deploy flink on yarn with multi hdfs cluster or hdfs > federation, Flink need to get delegation tokens of all the namespaces before > start appmaster. -- This message was sent by Atlassian Jira (v8.3.4#803005)
