Re: JobManager doesn't recover in HA mode

Hi Tony, Thanks for your response! I would definitely check supervisord. I wonder if there is a way that I can recover the killed JM and add it back to the cluster by using one of the scripts in the *flink/bin/* Thanks! Best regards, Mu On Thu, Feb 1, 2018 at 3:50 PM, Tony Wei

JobManager doesn't recover in HA mode

Hi all, I have a Flink HA cluster with 2 job managers and a zookeeper quorum of 3 nodes. My failed job manager didn't get recovered after I killed it. Here is how I didn't it and what I've observed: 1. I started the HA cluster with start-cluster.sh 2. Job manager A got elected. 3. I killed job

How to enable “upsert mode” for dynamic tables?

I'm relatively new to Flink, so apologies in advance if this is a simple question. I have seen several mentions of an "upsert mode" for dynamic tables based on a unique key in the Flink documentation and on the official Flink blog. However, I do not see any examples / documentation regarding how

Re: S3 for state backend in Flink 1.4.0

Hi Aljoscha, Thinking a little bit more about this, although IBM Object storage is compatible with Amazon's S3, it's not an eventually consistent file system, but rather immediately consistent. So we won't need the support for eventually consistent FS for our use case to work, but we would only

Re: RichAsyncFunction in Scala

Re: End-to-end exactly once from kafka source to S3 sink

"Flink will only commit the kafka offsets when the data has been saved to S3" -> no, you can check the BucketingSink code, and it would mean BucketingSink depends on Kafka which is not reasonable. Flink stores checkpoint in disk of each worker, not Kafka. (KafkaStream, the other streaming API

So there are three ways. 1. make your model as stream source 2. let master read the model once, distribute it via constructor, and update it periodically 3. let worker read the model and update it periodically(you mentioned) option 3 would be problematic if you scale a lot and use many

Re: How does BucketingSink generate a SUCCESS file when a directory is finished

it depends on how you partition your file. in my case I write file per hour, so I'm sure that file is ready after that hour period, in processing time. Here, read to be ready means this file contains all the data in that hour period. If the downstream runs in a batch way, you may want to ensure
