             Summary: LLAP : add LLAP IO read debug tool
                 Key: HIVE-10015
                 URL: https://issues.apache.org/jira/browse/HIVE-10015
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sergey Shelukhin


Need a tool that will run read pipeline on a file downloaded from the cluster (that causes some exception), for local debugging. Needs to reproduce whatever environment necessary (in IO pipeline itself) from the cluster (e.g. allocation sizes in allocator, etc.). Cache contents can be gotten from the same file (optional, phase 2); incorrect pre-existing cache contents would be out of the scope of this.
