Ted,

"fs.default.name" is a standard config property name which is described here:
http://hadoop.apache.org/common/docs/current/core-default.html

It is not CDH -specific. If you are right than this tool has never been tested.

Best regards,

Vlad:
In the future, please drop unrelated discussion from bottom of your email.

I think what you saw was caused by FS default name not being set correctly.
In hbck:
        conf.set("fs.defaultFS", conf.get(HConstants.HBASE_DIR));
But cdh3 uses:
    conf.set("fs.default.name", "hdfs://localhost:0");
./src/test/org/apache/hadoop/hdfs/server/namenode/TestCheckpoint.java

You can try adding the following line after line 77 of
OfflineMetaRepair.java:
    conf.set("fs.default.name", path);
and rebuilding hbase 0.90.6 (tip of 0.92 branch)

If the above works, please file a JIRA.

Thanks
