Yishan Yang created HBASE-17437: ----------------------------------- Summary: Support specifying WAL directory to different directory with different file system (For example: S3) Key: HBASE-17437 URL: https://issues.apache.org/jira/browse/HBASE-17437 Project: HBase Issue Type: Bug Affects Versions: 1.2.4 Reporter: Yishan Yang Fix For: 2.0.0, 1.2.5
Currently, the WAL and the StoreFiles need to be on the same FileSystem. Some FileSystems (such as Amazon S3) don’t support append or consistent writes. These two properties are imperative for the WAL in order to avoid loss of writes. However, StoreFiles don’t necessarily need the same consistency guarantees (since writes are cached locally and if writes fail, they can always be replayed from the WAL). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
