In our cluster, we has many SSD and a little HDD. (Most table configured storage policy ONE_SSD, and all wals is configured ALL_SSD) when all cluster down, It's difficult to recovery cluster. Because HDD Disk IO bottleneck (Almost all disk io util is 100%). I think the most hdfs operation when recovery is split wal to recovered edits dir, And read it. And it goes better when i stop hbase and set all recovered.edits to ALL_SSD. So we can get benifit of recovery time if we set recovered.edits dir to better storage like WAL. Now i reuse config item hbase.wal.storage.policy to set recovered.edits storage type. Because I did not find a scenario where they use different storage Policy -- This message was sent by Atlassian Jira (v8.20.1#820001)
