-------------------------------
Summary: Fixing performance and timeout issues in HDFS-7929: use
hard-links instead of copying edit logs
Key: HDFS-8480
URL: https://issues.apache.org/jira/browse/HDFS-8480
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Zhe Zhang
Assignee: Zhe Zhang
HDFS-7929 copies existing edit logs to the storage directory of the upgraded
{{NameNode}}. This slows down the upgrade process. This JIRA aims to use
hard-linking instead of per-op copying to achieve the same goal.
