>>> APAC/EMEA Community meeting
* The time of the second Community Sync:
Friday 12:15PM Beijing / 9:45AM India
* We agreed to use the same Zoom link as on Monday for the sake of
simplicity, but rooms seems to be assigned to hosts. I suggest to use
the existing/old link: https://cloudera.zoom.us/j/5780476042
>>> OzoneFS changes
* Marton quickly shared the project structure of ozonefs projects
* TLDR; use ozonefs-hadoop2/3 in external projects, ozonefs-shaded
does the shading, ozonefs-common contains all the important java code,
ozonefs is a non-shaded version (used by ozone fs command)
>>> Storage-class support
* There are some open questions which are summarized (and added to
the hackmd doc)
* https://hackmd.io/4kxufJBOQNaKn7PKFK_6OQ?edit
* How to configure? What is the level of abstraction?
* Transitions between storage-classes
* Required implementation changes?
* Mukul suggested to add more technical details (POC?).
* If I understood well there was an agreement about the concept, but
some questions depend on the exact implementation
>>> Upgrade design doc
* uploaded to HDDS-3698. An introduction can be done next Monday, id
Aravindan is available.
>>> OFS merge vote is on-going, please follow the thread
>>> Rocksdb performance problems on datanode
* The problem quickly summarized as it can be a big change
* Too many closed containers --> too many RocksDB handlers (+ memory,
+ threads)
* @runzhiwang is working actively on a proposal
*

>>> Unit test
* Mukul: Many integration tests are disabled, we should spend time on
fix then. Please fix one unit test per week, and we are done
* Code coverage data is uploaded to the Sonar. Acceptance test
coverage will be added soon.
* Vivek is working on an integration with pull requests (PR will be
commented with coverage information)
