Subject Re: JIRAs post-"unsplit"
Date Mon, 13 Jun 2011 18:51:44 GMT
I tend to agree: JIRA separation was the benefit of the split.

I'd rather keep the current JIRA split in effect (e.g. separate JIRA projects
for separate Hadoop components; don't recombine them) and file patches in the
same way (for common, hdfs, mapreduce). If a cross component patch is needed
then HADOOP project JIRA can be used for tracking, patches, etc.

Tree-based watch-list seems like a great idea, but won't it narrow the scope
somehow? Are you saying that if I am interested in say hdfs/src/c++/libhdfs,
but a JIRA is open which affects libhdfs and something else (e.g. NameNode) I
will still get the notification?
