             Summary: Tez Spill handler should truncate files to reserve space on disk
                 Key: TEZ-1277
                 URL: https://issues.apache.org/jira/browse/TEZ-1277
             Project: Apache Tez
          Issue Type: Improvement
    Affects Versions: 0.5.0
            Reporter: Gopal V
            Assignee: Gopal V


Occasionally tasks fail due to full disks because the disks had space when the task was allocating via LocalDirAllocator, but the disk space was actually promised to many tasks instead of just one.

This race condition shows up when a 1Gb spill can be done in ~10s or so.
