NOTE: I try to do my best to summarize the discussion, but there are so
many topics which I am not familiar very deeply, if you see any
inaccuracy, please reply and write your own opinion.
NOTE2: For the design docs I tried to add the names who are participated
in addition to the name who summarized the status during the call Again:
if I missed somebody, please ping me or reply.
* Mukul: SCM HA discussion
> Ongoing discussion based on the current draft (shared in JIRA)
> Community review meetings are planned after some conclusion
(if you are interested to participate in the current phase, ping
Xiaoyu/Mukul at ASF Slack)
* Uma: ViewFS (HDFS feature)
> Initial version will be published in next few weeks
> One open question: how the "mounting table" configuration is shared
(Options: 1) using XInclude tag 2) downloading config from HDFS?)
* Lokesh/Shashi/Mukul: Ozone Retry Policy Improvements (HDDS-3350)
> Design doc is uploaded, please comment
* Prashant: NFS support
> Design doc is already uploaded (TLDR: reuse HDFS code for NFS
gateway and follow that approach)
> It will be presented in the next Community Meeting
> A basic random-write support is included in the HDFS code (more
like a workaround) for the first phase it's proposed to be used
> long-term, native random read-write support is under discussion (a
new issue will be created)
* Prashant: Disk fault-injection framework
> FUSE based framework is used to inject io based failures to test
resiliency
> code is on github (fuse), details will be added to the cwiki
( source: https://github.com/prashantpogde/NoiseInjector)
> Open question: how can it be used for Ratis?
> Marton: it's very interesting and important topic and great work.
Would be great to share more details (eg. writing blog post, or do a
demo...)
* Next release is 0.6.0 (ideally in June)
> Roadmap wiki page [1] will be updated soon
> Spoiler alert, two main features:
> ofs://
> versioning of db files (upgrade support)
> Marton: would be great to keep the 3 moths release cadence. In
case of any longer delay, we can release the current master as a 0.5.1
* Marton: earlier we had a discussion to cleanup naming and refactor
the proto files
> Would be great to do this together with the versioning
> We already had a discussion and agreement, will try to find the
reference...
* Jitendra: time of this community meeting
> Proposed to move to Tuesday, same time. Will be further discussed
> Do we need a separated community / open call in Asia friendly time
zone? (Some of the existing syncs between APAC developers can be opened
/ made official if there is a demand)
* Xiaoyu: Upcoming change related the authorization
> We have specific code for to check if the user is "admin"
> Would be better to handle admin checks and other checks at the
same time
> (Required for better Ranger integration)
> More details coming soon.
