Jonathan Hsieh commented on HBASE-4377:
---------------------------------------
Todd too a quick look and mentioned that "fs.defaultFS" is a Hadoop 0.21+'ism.
On a 0.20.x release nothing really happens. Any concerns about this on the
0.90 backport?
{code}
+ public static void main(String[] args) throws Exception {
+
+ // create a fsck object
+ Configuration conf = HBaseConfiguration.create();
+ conf.set("fs.defaultFS", conf.get(HConstants.HBASE_DIR));
+ HBaseFsck fsck = new HBaseFsck(conf);

> In a worst case situation, it may be helpful to have an offline .META.
> rebuilder that just looks at the file system's .regioninfos and rebuilds meta
> from scratch. Users could move bad regions out until there is a clean
> rebuild.
> It would likely fill in region split holes. Follow on work could given
> options to merge or select regions that overlap, or do online rebuilds.
