Subject [jira] Commented: (HADOOP-7133) CLONE to COMMON - HDFS-1445 Batch the calls in DataStorage to FileUtil.createHardLink(), so we call it once per directory instead of once per file

    [ https://issues.apache.org/jira/browse/HADOOP-7133?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004329#comment-13004329

Jakob Homan commented on HADOOP-7133:
-------------------------------------

bq. I will resubmit part-2, attached to this issue, as soon as part-1 has been approved and
committed.
I had interpreted this to mean there would be a new HDFS patch.  Sounds like I'm incorrect
and the current patch there is the one you're submitting?

> 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.
