Thanks. My Program read hundreds of small files from s3 by SQL. What has happened in the instantiation of the SplitEnumerator? What can i do to reduce the time now?

The cause of this issue is likely because the instantiation of the SplitEnumerator is done in the JM main thread. FLINK-22282 has been created to address this issue. Thanks, Jiangjie (Becket) Qin On Wed, Apr 14, 2021 at 10:32 PM Piotr Nowojski <pnowoj...@apache.org> wrote: Hi, I haven't found anything strange in the logs (I've received logs in a separate message). It looks like the problem is that split enumeration is taking a long time, and currently this is being done in the Job Manager's main thread, blocking other things from executing. For the time being I think the only thing you can do is to either speed up the split enumeration (probably difficult) or increase the timeouts that are failing. I don't know if there is some other workaround at the moment (Becket?).
