Uma Maheswara Rao G commented on HDFS-2006:
-------------------------------------------

-1 core tests. The patch failed these unit tests in
hadoop-common-project/hadoop-common hadoop-hdfs-project/hadoop-hdfs:
org.apache.hadoop.hdfs.tools.offlineEditsViewer.TestOfflineEditsViewer
{quote}
This failure is expected as editsStored binary file can not be included in
patch. On committing that binary file along with edirsStored binary file this
test will pass.
So, all *checks passed with merge patch*.
I will generate another merge patch today with latest checkins in the branch.

> It would be nice if HDFS provides a feature to store extended attributes for
> files, similar to the one described here:
> http://en.wikipedia.org/wiki/Extended_file_attributes.
> The challenge is that it has to be done in such a way that a site not using
> this feature does not waste precious memory resources in the namenode.
