László Bodor updated HIVE-28165:
--------------------------------
Description:
After some investigations regarding hive iceberg issues, it turned out that in
the presence of delete files, the serialized payload might be huge, like 1-4MB
/ split, which might lead to extreme memory pressure in the Tez AM, getting
worse while more and more splits.
Optimizing the payload is always the best option but it's not that obvious:
instead we should make hive and tez together take care of such situations
without running into OOMs like this below:
