Subject [jira] [Updated] (HDFS-8122) Erasure Coding: Support specifying ECSchema during creation of ECZone
Date Mon, 13 Apr 2015 11:49:13 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8122?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinayakumar B updated HDFS-8122:
--------------------------------
    Attachment: HDFS-8122-02.patch

Thanks [~umamaheswararao] for the review.
I have updated the return value as below.
{code}
      ECSchema schema = dir.getECSchema(iip);
      if (schema != null) {
        return new ECInfo(src, schema);
      }
{code}

Now, always a zone will carry schema in xattr (either user specified or default)
If not having schema, then the directory is not an EC zone. So returning {{null}}.
