------------------------------------
Summary: Configuration does not substitute multiple references to
the same var
Key: HADOOP-13699
URL: https://issues.apache.org/jira/browse/HADOOP-13699
Project: Hadoop Common
Issue Type: Bug
Components: conf
Affects Versions: 3.0.0-alpha1
Reporter: Andrew Wang
Assignee: Andrew Wang
Priority: Critical
Config var loop detection was originally introduced by HADOOP-6871. Due to
cycle detection changes in the trunk patch for HADOOP-11506, resolution for
multiple references to the same variable no longer resolved, e.g.
{noformat}
somekey = "${otherkey} ${otherkey}"
{noformat}
This loop detection business is fragile, expensive, and not in branch-2, so
let's reduce it.
