>>> Jitendra: What is the current state of our CSI implementation?
--> Marton: CSI server is implemented and should work (can be retested)
--> But the tricky part is the mount (how to mount one Ozone bucket)
This is not part of CSI spec. In the current code, goofyfs is
hard-coded. But we can make it configurable to support NFS, or
experimental Ozone Fuse implementations.
--> S3 performance? We don't have recent numbers. We can measure it.
--> proxy user usage?: One possible performance problem: we create a
new Ozone client for each HTTP request. Should be possible to address it.
>>> Arpit: ofs:// status
--> (note ofs:// uses new scheme: ofs://om:port/vol1/bucket1/...)
--> almost functional complete
--> should be tested with all downstream components
--> one potential (breaking?) change is the behavior of /tmp (first
level directories are volumes, only second level directories are
writable...)
--> Clay share some potential HBase/Hive problems and usage of
sticky bits (not yet supported)
>>> Jitendra: Shashi was able to execute YCSB Hbase benchmark (with
some flush/sync workarounds)
>>> Arpit: HDDS-3155. might need some community discussion and
clarification
>>> Marton: List of old design docs will be part of doc:
https://github.com/apache/hadoop-ozone/pull/755
--> It might be a good idea to update it as part of the design
process (proposed earlier [1])
--> But adding just at the the end of the implementation of a feature
(where we should update docs anyway) also can help to find it later
>>> Marton: Some work can be expected on current/legacy ozonefs jar
--> current legacy doesn't work with secure Ozone and has a very
complex classloader separation
--> There could be a way to simplify it to remove some Hadoop
dependencies
--> For example to use a ConfigurationSource interface instead of
OzoneConfiguration, but keep OzoneConfiguration/o.a.hadoop.Configuration
as the implementation (see HDDS-3101)
>>> Stephen: new #ozone_topology channel is opened on the Apache Slack.
Please join if you are interested
>>> In-progress design discussions
---> Viewfs improvements on HDFS side (WIP), will be published soon
---> s3/volume mapping: last call to comment (open pull request)
---> NFS: uploaded, discussion in comments (HDDS-3001)
---> SCM-HA: No update, AFAIK
