Matt Foley commented on HADOOP-7133:
------------------------------------

Hi Jakob, the HDFS counterpart has been up for some time on HDFS-1445.  However, test-patch can't run against the HDFS part until this COMMON part has been committed.  So perhaps it would be best if you take a quick look at HDFS-1445, then commit this patch so that I can enable test-patch to run against the other part?  Thanks.

> The fix for HDFS-1445 "Batch the calls in DataStorage to FileUtil.createHardLink(), so we call it once per directory instead of once per file" requires coordinated change in COMMON and HDFS.  This is the COMMON portion, submitted here under a separate bug to activate the automated testing.
> Warning: this patch to COMMON, by itself, will break HDFS.  It requires coordinated commit of the HDFS portion of the patch in HDFS-1445.
