[jira] [Created] (FLINK-22816) Investigate feasibility of supporting multiple RM leader sessions within JM process
Xintong Song created FLINK-22816: Summary: Investigate feasibility of supporting multiple RM leader sessions within JM process Key: FLINK-22816 URL: https://issues.apache.org/jira/browse/FLINK-22816 Project: Flink Issue Type: Improvement Components: Runtime / Coordination Reporter: Xintong Song In FLINK-21667, we decoupled RM leadership and lifecycle managements. RM is not started after obtaining leadership, and stopped on losing leadership. Ideally, we may start and stop multiple RMs, as the process obtains and loses leadership. However, as discussed in the [PR|https://github.com/apache/flink/pull/15524#pullrequestreview-663987547], having a process to start multiple RMs may cause problems in some deployment modes. E.g., repeated AM registration is not allowed on Yarn. We need to investigate for all deployments that: - Whether having multiple leader sessions causes problems. - If it does, what can we do to solve the problem. For information, multi-leader-session support for RM has been implemented in FLINK-21667, but is disabled by default. To enable, add the system property "flink.tests.enable-rm-multi-leader-session". -- This message was sent by Atlassian Jira (v8.3.4#803005)
How to use or configure flink checkpointing with siddhi internal state
Hi , I was trying to do checkpointing while using siddhi as the CEP engine running on flink. While using siddhi windowing , it uses an internal state to aggregated or perform operation on a bucket of events pertaining to a specific time window. But what i am not sure is how can that state be mapped to Flinks internal state so that i can use flink checkpointing to safeguard the internal state of the siddhi operators in the face of failure. Any help or pointer for this will be of great help to me.Thanks in advance. Dipanjan -

[DISCUSS] Dashboard/HistoryServer authentication
Hi team, Firstly I would like to introduce Gabor or G [1] for short to the community, he is a Spark committer who has recently transitioned to the Flink Engineering team at Cloudera and is looking forward to contributing to Apache Flink. Previously G primarily focused on Spark Streaming and security. Based on requests from our customers G has implemented Kerberos and HTTP Basic Authentication for the Flink Dashboard and HistoryServer. Previously lacked an authentication story. We are looking to contribute this functionality back to the community, we believe that given Flink's maturity there should be a common code solution for this general pattern. We are looking forward to your feedback on G's design. [2] [1] http://gaborsomogyi.com/ [2] https://docs.google.com/document/d/1NMPeJ9H0G49TGy3AzTVVJVKmYC0okwOtqLTSPnGqzHw/edit

Re: [DISCUSS][Statebackend][Runtime] Changelog Statebackend Configuration Proposal
Hey Yuan, thanks for the proposal I think Option 3 is the simplest to use and exposes less details than any other. It's also consistent with the current way of configuring state backends, as long as we treat change logging as a common feature applicable to any state backend, like e.g. state.backend.local-recovery. Option 6 seems slightly less preferable as it exposes more details but I think is the most viable alternative.

Re: [ANNOUNCE] Apache Flink 1.13.1 released
Hi Youngwoo, Usually we publish the docker images a day after the general release, so that the artifacts are properly distributed across Apache mirrors. You should be able to download the docker images from apache/flink now. It may take a few extra days to have the images published as the official image, as it depends on the maintainers of docker hub.

[DISCUSS][Statebackend][Runtime] Changelog Statebackend Configuration Proposal
Hey all, We would like to start a discussion on how to enable/config Changelog Statebakcend. As part of FLIP-158[1], Changelog state backend wraps on top of existing state backend (HashMapStateBackend, EmbeddedRocksDBStateBackend and may expect more) and delegates state changes to the underlying state backends. This thread is to discuss the problem of how Changelog StateBackend should be enabled and configured. Proposed options to enable/config state changelog is listed below: Option 1: Enable Changelog Statebackend through a Boolean Flag Option 2: Enable Changelog Statebackend through a Boolean Flag + a Special Case Option 3: Enable Changelog Statebackend through a Boolean Flag + W/O ChangelogStateBackend Exposed Option 4: Explicit Nested Configuration + “changelog.inner” prefix for inner backend Option 5: Explicit Nested Configuration + inner state backend configuration unchanged Option 6: Config Changelog and Inner Statebackend All-Together Details of each option can be found here: https://docs.google.com/document/d/13AaCf5fczYTDHZ4G1mgYL685FqbnoEhgo0cdwuJlZmw/edit?usp=sharing When considering these options, please consider these four dimensions: 1 Consistency API/config should follow a consistent model and should not have contradicted logic beneath 2 Simplicity API should be easy to use and not introduce too much burden on users 3. Explicity API/config should not contain implicit assumptions and should be intuitive to users 4.
