Subject [jira] Commented: (HADOOP-5188) Modifications to enable multiple types of logging
Date Sat, 23 May 2009 11:01:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5188?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712406#action_12712406

Flavio Paiva Junqueira commented on HADOOP-5188:

I'd like to make a comment and ask a question:

1- There are two files missing license headers. Before submitting a patch, please make sure
that all new files have a license header. Also, according to Hudson, this patch introduces
new potential bugs according to findbugs. Pleas verify if they can be fixed;

2- Using BookKeeper as an example, I was wondering where we will store the configuration parameters
necessary to bootstrap and run it as a log device. For example, we need to specify number
of bookies and ledger mode. If I understand it correctly, the idea is to pass these parameters
in a URI, and then parse the URI. Once the namenode parses the URI, it will have the values
for the corresponding variables, and it will keep it somewhere. Is the idea to keep such configuration
parameters in the corresponding log device implementation for BookKeeper?
