Jingsong Lee commented on FLINK-15527:
--------------------------------------
Hi [~chenchencc], you can add config option
"table.exec.hive.infer-source-parallelism.max" to "flink-conf.yaml" to limit
source parallelism. (This config option is experimental feature)
> can not control the number of container on yarn single job module

> when run yarn single job run many container but paralism set 4
> *scripts:*
> ./bin/flink run -m yarn-cluster -ys 3 -p 4 -yjm 1024m -ytm 4096m -yqu bi -c
> com.cc.test.HiveTest2 ./cc_jars/hive-1.0-SNAPSHOT.jar 11.txt test61 6
> _notes_: in 1.9.1 has cli paramter -yn to control the number of containers
> and in 1.10 remove it
> *result:*
> the number of containers is 500+
>
> *code use:*
> query the table and save it to the hdfs text
>
> the storge of table is 200g+
