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}}
