[jira] [Commented] (ORC-42) Advance Hadoop Architecture (AHA) -
Advance ORC (Umbrella) JIRA
[ https://issues.apache.org/jira/browse/ORC-42?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17180682#comment-17180682 ]
Dinesh S. Atreya commented on ORC-42:
-------------------------------------
Now Hadoop Distributed Data Store is an active effort, starting with _Hadoop Distributed Storage Layer (HDSL)_ HDFS-7240, *Ozone File System* (aka Hadoop Distributed Data Store) HDFS-13074 after formally being named with *Ozone: Rename HDSL to HDDS* HDFS-13405.
Ozone is built on a highly available, replicated block storage layer called Hadoop Distributed Data Store (HDDS) and is S3 compatible. Ozone can function effectively in containerized environments such as _*Kubernetes*_ and _*YARN*_. Ozone supports different protocols like S3 and Hadoop File System APIs.
Work on this JIRA and related JIRAs are using S3 compatible Ozone as a base.
