> Our use case is as follows,
> # hive source: create hive table which meta data is in HMS
> # create hbase use hbase shell
> # flink sql ddl: create hbase flink table
> # use hive catalog: use flink sql insert into hbase flink table
> if i set the tableconfig: table.exec.hive.infer-source-parallelism = false
> The program will run as one parallelism，and the number of records of results
> is correct.
> but if i set the tableconfig: table.exec.hive.infer-source-parallelism = true
> The program will run as twenty parallelism that express source parallelism is
> inferred according to splits number，and the number of records of results is
> not correct.
>
> The test was repeated many times and there was no exception occurred.
>
> So I guess it has something to do with high concurrency. Does it lose data
> because of high concurrency?
