Zhe Zhang commented on HDFS-8077:
---------------------------------
Thanks Jing! The fixes look good to me overall.
bq. While processing block report we need to do a copy for the reported block
of BlockToMarkCorrupt since the block report processing reuses the same block
object.
I don't fully understand this yet. Does the fix apply to both contiguous and
striped blocks? If so it should go into trunk?

>
> EC zone manager tries to get XAttr of an inode to determine the EC policy,
> which doesn't work with symlinks. This patch has a simple fix to get rid of
> test failures.
> Ideally we should also add logic to disallow creating symlinks in several
> EC-related scenarios. But since symlinks are disabled in branch-2 and will
> likely be disabled in trunk, this step is skipped now.
> The patch also fixes a small test error around {{getBlockReplication}}
