-----------------------------------

             Summary: Change "java.io.tmpdir"  of JM/TM on Yarn to "{{PWD}}/tmp"
                 Key: FLINK-15447
                 URL: https://issues.apache.org/jira/browse/FLINK-15447
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / YARN
    Affects Versions: 1.9.1
            Reporter: Victor Wong


Currently, when running Flink on Yarn, the "java.io.tmpdir" property is set to the default value, which is "/tmp". 

 

Sometimes we ran into exceptions caused by a full "/tmp" directory, which would not be cleaned automatically after applications finished.

I think we can set "java.io.tmpdir" to "\{{PWD}}/tmp" directory, or something similar. "\{{PWD}}" will be replaced with the true working directory of JM/TM by Yarn, which will be cleaned automatically.
