[jira] [Updated] (HADOOP-9668) Configuration#iterator method should
interpret variables in a property as well as Configuration#get method
[ https://issues.apache.org/jira/browse/HADOOP-9668?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kousuke Saruta updated HADOOP-9668:
-----------------------------------
Description:
o.a.h.conf.Configuration#get method interpret variables in a property in *-site.xml but Configuration#iterator method don't.
For example, when a property "user.name" is set to "hadoop" and another property "hadoop.tmp.dir" is set to "/tmp/$${user.name}", Configuration#get interpret "hadoop.tmp.dir" as "/tmp/hadoop" but Configuration#iterator don't interpret.
I think Configuration#iterator should interpret variables or if there are some reasons, it should be documented that Configuration#iterator don't interpret variables.

I think Configuration#iterator should interpret variables or if there are some reasons, it should be documented that Configuration#iterator don't interpret variables.
