Subject [jira] Commented: (HADOOP-6184) Provide a configuration dump in json format.
Date Thu, 20 Aug 2009 10:27:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745379#action_12745379

Hemanth Yamijala commented on HADOOP-6184:
------------------------------------------

- updatingResouce need not be static. Also, I think it should not be created unless the flag
to store resources is set to true.
- Leave a space between control statement (like if) and the condition
- Rename writeJson to dumpConfiguration. Document in writeJson that it will not work if configuration
is loaded from the an input stream. Update documentation to say the format in which the dump
is generated. It would also be good to document the format itself as an example.
- Why is flush called after each item written ? Can it be done only once ?
- Should handle the case where default resources are not loaded. When a configuration object
is cloned in writeJson, it loses knowledge of whether default resources were loaded with the
original config being dumped or not.
- Testcase: 
-- the writers created should be closed.
-- the way we are looking up for the key from the json properties can do with some improvement.
Can't we build a hashtable once the deserialization happens and do a lookup ?
