[jira] [Updated] (SPARK-45604) Converting timestamp_ntz to array can cause NPE or SEGFAULT on parquet vectorized reader
[ https://issues.apache.org/jira/browse/SPARK-45604?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zamil Majdy updated SPARK-45604:
--------------------------------
Description:
Repro:
```
spark.conf.set("spark.databricks.photon.enabled", "false")
val path = "/tmp/zamil/timestamp"
val df = sql("SELECT MAP('key', CAST('2019-01-01 00:00:00' AS TIMESTAMP_NTZ)) AS field")
df.write.mode("overwrite").parquet(path)
spark.read.schema("field map<string, array<timestamp_ntz>>").parquet(path).collect()
```
Depending on the memory mode is used, it will produced NPE on on-heap mode, and segfault on off-heap
