> support specify config items through system property
> ----------------------------------------------------
>
> Key: HADOOP-9223
> URL: https://issues.apache.org/jira/browse/HADOOP-9223
> Project: Hadoop Common
> Issue Type: Improvement
> Components: conf
> Affects Versions: 2.0.0-alpha
> Reporter: Zesheng Wu
> Priority: Minor
> Labels: configuration, hadoop
> Fix For: 2.0.0-alpha
>
> Attachments: HADOOP-9223.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> 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 in
> 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
> If this patch is applied, then people can start hadoop programs in this way:
> java -cp $class_path -Dhadoop.property.$name=$value $program
