Subject [jira] [Created] (HDFS-8077) Erasure coding: fix bug in EC zone and symlinks
Date Tue, 07 Apr 2015 20:58:12 GMT
Zhe Zhang created HDFS-8077:

             Summary: Erasure coding: fix bug in EC zone and symlinks
                 Key: HDFS-8077
                 URL: https://issues.apache.org/jira/browse/HDFS-8077
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Zhe Zhang
            Assignee: Zhe Zhang

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}}
