----------------------------------
Summary: Ozone DataNode does not set
raft.server.log.corruption.policy to the RaftServer implementation it uses
Key: HDDS-2647
URL: https://issues.apache.org/jira/browse/HDDS-2647
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: Ozone Datanode
Reporter: Istvan Fajth
In the XceiverServerRatis class which is used by the DataNode as well to create
the RaftServer implementation that is used, there is a method called
newRaftProperties() which is there to set up the RaftProperties object
specified for the RaftServer it starts.
This method is pretty hard to keep in sync with all the ratis properties, and
due to an issue where I was turned to RATIS-677 which introduced a new
configuration, I was not able to set this new property via the DataNode's
ozone-site.xml, as it was not forwarded to the Ratis server.
On the long run we would need a better implementation that does not need tuning
and follow up for every new Ratis property, however at the moment as a wuick
fix we can just provide the property. Depending on the implementor, if we go
with the easy way, then please create a new JIRA for a better solution after
finishing this one. Also if I am wrong, and Ratis properties can be defined for
the DN properly elsewhere, please let me know.
As OM is also using Ratis in HA configuration, this one should be checked there
as well, however this one is not really important until RATIS-762 is fixed.
