Colin Patrick McCabe created HDFS-3947: ------------------------------------------
Summary: If there are multiple edit logs with the same fstime, Recovery Mode should load a different one than the normal loading process Key: HDFS-3947 URL: https://issues.apache.org/jira/browse/HDFS-3947 Project: Hadoop HDFS Issue Type: Improvement Affects Versions: 1.2.0 Reporter: Colin Patrick McCabe Assignee: Colin Patrick McCabe Priority: Minor If there are multiple edit logs with the same {{fstime}}, Recovery Mode should load a different one than the normal loading process. This will protect against many common kinds of corruption which affect only one edit log directory. For example, most I/O errors would fall into this category. This improvement is not necessary in branch-2 and later branches because in those branches, we have edit log failover (See HDFS-3049). However, this is an extremely simple and useful thing we can do to make Recovery Mode more helpful in branch-1. -- This message is automatically generated by JIRA.
