----------------------------------------
Summary: DataNode Container reads/Writes should be disallowed for
open containers if the replication type mismatches
Key: HDDS-162
URL: https://issues.apache.org/jira/browse/HDDS-162
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Datanode, SCM
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Fix For: 0.2.1
In Ozone, container can be created via ratis or Standalone protocol. However,
the reads/.writes on the containers on datanodes can be done through either of
these if the container location is known. A case may arise where data is being
written into container via Ratis i.e, the container is in open State on the
Datanodes and read via Standalone. This should not be allowed as if the read
from the follower Datanodes in Ratis via Standalone Protocol might result in
giving stale data. Once the container is closed on the datanode, data can be
read via either of the protocols.
