Stephen Chu created HDFS-4048:
---------------------------------
Summary: Use ERROR instead of INFO for volume failure logs
Key: HDFS-4048
URL: https://issues.apache.org/jira/browse/HDFS-4048
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.0.0-alpha
Reporter: Stephen Chu
Assignee: Stephen Chu
Fix For: 3.0.0, 2.0.3-alpha
I misconfigured the permissions of the DataNode data directories (they were
owned by root, instead of hdfs).
I wasn't aware of this misconfiguration until a few days later. I usually
search through the logs for WARN and ERROR but didn't find messages at these
levels that indicated volume failure.
After more carefully reading the logs, I found:
{code}
2012-10-01 13:07:10,440 INFO org.apache.hadoop.hdfs.server.common.Storage:
Cannot access storage directory /data/4/dfs/dn
2012-10-01 13:07:10,440 INFO org.apache.hadoop.hdfs.server.common.Storage:
Storage directory /data/4/dfs/dn does not exist.
{code}
I think we should bump the log level to ERROR. This will make the problem more
visible to users.
