[jira] [Created] (HIVE-17195) Long chain of tasks created by REPL LOAD shouldn't cause stack corruption.

Sankar Hariappan created HIVE-17195:
---------------------------------------

             Summary: Long chain of tasks created by REPL LOAD shouldn't cause stack corruption.
                 Key: HIVE-17195
                 URL: https://issues.apache.org/jira/browse/HIVE-17195
             Project: Hive
          Issue Type: Sub-task
          Components: HiveServer2, repl
    Affects Versions: 2.1.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan
             Fix For: 3.0.0


Currently, long chain REPL LOAD tasks lead to huge recursive calls when try to traverse the DAG.
For example, getMRTasks, getTezTasks, getSparkTasks and iterateTasks methods run recursively to traverse the DAG.
Need to modify this traversal logic to reduce stack usage.
