Harsh J created HADOOP-8532:
-------------------------------
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.
