------------------------------
Summary: Make cluster-wide EC configuration take effect.
Key: HDDS-6294
URL: https://issues.apache.org/jira/browse/HDDS-6294
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Mark Gui
Assignee: Kaijie Chen
By reading through the doc ErasureCoding.md, I found 2 configs for
cluster-level EC:
<property>
<name>ozone.server.default.replication.type</name>
<value>EC</value>
</property>
<property>
<name>ozone.server.default.replication</name>
<value>RS-6-3-1024k</value>
</property>
But by referring to the latest code of HDDS-3816-ec, the enums defined are
never referenced
public static final String OZONE_SERVER_DEFAULT_REPLICATION_KEY =
"ozone.server.default.replication";
public static final String OZONE_SERVER_DEFAULT_REPLICATION_DEFAULT =
ReplicationFactor.THREE.toString();
public static final String OZONE_SERVER_DEFAULT_REPLICATION_TYPE_KEY =
"ozone.server.default.replication.type";
public static final String OZONE_SERVER_DEFAULT_REPLICATION_TYPE_DEFAULT =
ReplicationType.RATIS.toString();
IMO, the 2 configs should be checked in
OzoneConfigUtil#resolveReplicationConfigPreference() as a fallback if no
bucket-level policy is specified,
or we could make the change in OzoneManager#getDefaultReplicationConfig()
which now refer to "ozone.replication" and "ozone.replication.type".
