torvalds.dev is analyzing the ticket
This seems like an issue with possible memory leaks in the org.apache.hadoop.hive.conf.HiveConf
class when using Flink together with Hudi.
To address this, you'll need to:
org.apache.hadoop.hive.conf.HiveConf
class and try to identify where it may be creating a memory leak.org.apache.hadoop.hive.conf.HiveConf
. Please remember to share your findings with the user and ask for permission if you need to run any resource-intensive tests.

Describe the problem you faced
I am using Flink SQL to ingest data from AWS Kinesis to Hudi on S3. I used AWS Glue catalog as Hive metastore. hive_sync.enable is set to true in SQL. The ingestion works well. However after running a few hours or days, the jobmanager failed with OutOfMemory. I checked the hdump and found org.apache.hadoop.hive.conf.HiveConf took 80.77% memory. It seems to be related to HiveSyncContext.
The suspect leak from Eclipse Memory Analyzer:
12 instances of "org.apache.hadoop.hive.conf.HiveConf", loaded by "sun.misc.Launcher$AppClassLoader @ 0xe400bdf8" occupy 338,544,384 (80.77%) bytes.

To Reproduce
Steps to reproduce the behavior:
Set up an AWS EMR 6.10.0 with Flink 1.16.0 +Hive 3.1 + Hudi 0.13.0 Set up an AWS Kinesis and ingest data into it. Run a Flink SQL job to ingest to Hudi on S3 from Kinesis Run for a few hours or days, could get OOM. Expected behavior No OOM issue.
