Update TestDFSUpgradeFromImage to test batch hardlink improvment ----------------------------------------------------------------
Key: HDFS-1622 URL: https://issues.apache.org/jira/browse/HDFS-1622 Project: Hadoop HDFS Issue Type: Improvement Reporter: Hairong Kuang Matt has done a great job in HDFS-1443 that uses batch link command to improve datanode upgrade performance. However TestDFSUpgradeImage upgrades from an image layout of -7 which is too old to test the batch feature. We need to update this test to use a more recent layout. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
