[jira] [Created] (FLINK-27911) Set HDFS LEASE_TIMEOUT as user-configurable

zoucao created FLINK-27911:
------------------------------

             Summary: Set HDFS LEASE_TIMEOUT as user-configurable
                 Key: FLINK-27911
                 URL: https://issues.apache.org/jira/browse/FLINK-27911
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.12.2
            Reporter: zoucao
         Attachments: exceptions

The HDFS LEASE_TIMEOUT in *HadoopRecoverableFsDataOutputStream* is set to 100_000 millis, In some cases, 100 seconds is not enough. In our company, when using StreamingFileSink to write records to HDFS and the parallelism is set to 512 or larger, the following exceptions occur frequently. I think we can update the parameter LEASE_TIMEOUT as user-configurable.
