ketkidev opened a new issue, #9958:
URL: https://github.com/apache/hudi/issues/9958
**Describe the problem you faced**
In **Hudi 0.14** when running our application where more than one tables are
processed and upserted at a time using multithreading, we get this error once
in a while (generally once in an hour). It also gets resolved automatically in
the second or third retry. It's not happening in when tables are upserted in
serialize manner. At a time we are trying to upsert 6-7 tables.
Please note we never observed this issue in 0.13 while upserting multiple
tables at a time.
**To Reproduce**
Example of a Hudi MOR Table configuration:
```
{
'hoodie.table.name': asset,
'hoodie.datasource.write.recordkey.field': id,
'hoodie.datasource.write.table.name': asset,
'hoodie.upsert.shuffle.parallelism': 400,
'hoodie.keep.max.commits': 50,
'hoodie.keep.min.commits': 49,
'hoodie.compact.inline.max.delta.commits': 6,
'hoodie.clean.automatic': 'false',
'hoodie.clean.async': 'false'
'hoodie.datasource.write.operation': 'upsert',
'hoodie.datasource.write.precombine.field': 'cdc_timestamp',
'hoodie.datasource.write.table.type': 'MERGE_ON_READ',
'hoodie.cleaner.policy': 'KEEP_LATEST_COMMITS',
'hoodie.schema.on.read.enable' : "true",
'hoodie.datasource.write.reconcile.schema' : "true",
'hoodie.compact.inline' : "true",
'hoodie.datasource.write.keygenerator.class':
'org.apache.hudi.keygen.NonpartitionedKeyGenerator',
'hoodie.metadata.max.deltacommits.when_pending' : 2000
}
```
**Expected behavior**
A smooth upsert in all tables.
**Environment Description**
* Hudi version : 0.14.0
* Spark version : 3.4.1
* Storage (HDFS/S3/GCS..) : S3
* Running on Docker? (yes/no) : no
**Stacktrace**
```
Could not upsert into Hudi table. While upserting, encountered this error -
An error occurred while calling o511.save.
