             Summary: [Configuration] Increase or make variable substitution depth configurable
                 Key: HADOOP-8532
                 URL: https://issues.apache.org/jira/browse/HADOOP-8532
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
    Affects Versions: 2.0.0-alpha
            Reporter: Harsh J


We've had some users recently complain that the default MAX_SUBST hardcode of 20 isn't sufficient for their substitution needs and they wished it were configurable rather than having to roll about with workarounds such as using temporary smaller substitutes and then building the fuller one after it. We should consider raising the default hardcode, or provide a way to make it configurable instead.

Related: HIVE-2021 changed something similar for their HiveConf classes.
