Dyno created HADOOP-17201:
-----------------------------
Summary: Spark job stuck at the last stage
Key: HADOOP-17201
URL: https://issues.apache.org/jira/browse/HADOOP-17201
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Affects Versions: 3.2.1
Environment: we are on spark 2.4.5/hadoop 3.2.1 with s3a committer.
spark.hadoop.fs.s3a.committer.magic.enabled: 'true'
spark.hadoop.fs.s3a.committer.name: magic
Reporter: Dyno
Attachments: exec-120.log, exec-125.log, exec-25.log, exec-31.log,
exec-36.log, exec-44.log, exec-5.log, exec-64.log, exec-7.log
usually our spark job took 1 hour or 2 to finish, occasionally it runs for more
than 3 hour and then we know it's stuck and usually the executor has stack like
this
```
