----------------------------------------
Summary: support specify config items through system property
Key: CONFIGURATION-522
URL: https://issues.apache.org/jira/browse/CONFIGURATION-522
Project: Commons Configuration
Issue Type: Improvement
Components: Interpolation
Affects Versions: 2.x
Reporter: Zesheng Wu
Priority: Minor
Fix For: 2.x
The current hadoop config items are mainly interpolated from the *-site.xml
files. In our production environment, we need a mechanism that can specify
config items through system properties, which is something like the gflags for
system built with C++, it's really very handy.
The main purpose of this patch is to improve the convenience of hadoop systems,
especially when people do testing or perf tuning, which always need to modify
the *-site.xml files
