Jingsong,

I created https://issues.apache.org/jira/browse/FLINK-15928 to track the issue. Let me know if you need anything else to debug.

Thanks,
Fanbin

Hi Fanbin,

you could use the RC1 of Flink that was created yesterday and use the apache repo https://repository.apache.org/content/repositories/orgapacheflink-1325/org/apache/flink/flink-json/1.10.0/ .
Alternatively, if you build Flink locally with `mvn install`, then you could use mavenLocal() in your gradle.build and feed from that.

Best,

I can build flink 1.10 and install it on to EMR (flink-dist_2.11-1.10.0.jar). but what about other dependencies in my project build.gradle, ie. flink-scala_2.11, flink-json, flink-jdbc... do I continue to use 1.9.0 since there is no 1.10 available?

Thanks,
Fanbin

Hi Fanbin，

You can install your own Flink build in AWS EMR, and it frees you from Emr’s release cycles

Fanbin,

I have no idea now, can you created a JIRA to track it? You can describe complete SQL and some data informations.

Jingsong,

I set the config value to be too large. After I changed it to a smaller number it works now!
thanks you for the help. really appreciate it!

Fanbin,

Looks like your config is wrong, can you show your config code?

NOTE: you need configure this into TableConfig.

Jingsong,

Thank you for the response.
Since I'm using flink on EMR and the latest version is 1.9 now. the second option is ruled out. but will keep that in mind for future upgrade.

I'm going to try the first option. It's probably a good idea to add that in the doc for example: https://ci.apache.org/projects/flink/flink-docs-stable/ops/config.html

Thanks,
Fanbin

Hi Fanbin,

Thanks for using blink batch mode.

The OOM is caused by the manage memory not enough in Hash aggregation.

There are three options you can choose from:

1.Is your version Flink 1.9? 1.9 still use fix memory configuration. So you need increase hash memory:
- table.exec.resource.hash-agg.memory: 1024 mb

2.In 1.10, we use slot manage memory to dynamic config real operator memory, so operator can use more manage memory, so you don't need configure hash agg memory anymore. You can try 1.10 RC0 [1]

3.We can use sort aggregation to avoid OOM too, but there is no config option now, I created JIRA to track it. [2]

tried to increase memory:
flink run  -m yarn-cluster -p 16 -ys 1 -ytm 200000 -yjm 8096 myjar
and still got the same OOM exception.
my sql is like:
select id, hop_end(created_at, interval '30' second, interval '1' minute), sum(field)... #20 of these sums
from table group by id, hop(created_at, interval '30' second, interval '1' minute)

Hi,

I have a batch job using blink planner. and got the following error. I was able to successfully run the same job with flink 1.8 on yarn.

I set conf as:
