Aditya Goenka created HUDI-7461:
-----------------------------------
Summary: Date columns showing incorrect integer values while doing
CDC read
Key: HUDI-7461
URL: https://issues.apache.org/jira/browse/HUDI-7461
Project: Apache Hudi
Issue Type: Bug
Components: incremental-query
Reporter: Aditya Goenka
Fix For: 0.15.0
Date columns are showing integer values while doing CDC read.
For timestamp columns also it is converting into epoch , may be doing similar
conversion for date column causing wrong integer values.
Reproducible Code -
```
columns = ["ts","uuid","rider","driver","fare","city", "report_date"]
data
=[(1695159649087,"334e26e9-8355-45cc-97c6-c31daf0df330","rider-A","driver-K",19.10,"san_francisco",
"2022-01-01"),
(1695091554788,"e96c4396-3fad-413a-a942-4cb36106d721","rider-B","driver-L",27.70
,"san_francisco", "2022-01-01"),
(1695046462179,"9909a8b1-2d15-4d3d-8ec9-efc48c536a00","rider-C","driver-M",33.90

inserts = spark.createDataFrame(data).toDF(*columns)
hudi_options = {
'hoodie.table.name': tableName,
'hoodie.datasource.write.recordkey.field' : 'uuid',
'hoodie.datasource.write.precombine.field' : 'ts',
'hoodie.datasource.write.partitionpath.field': 'city',
'hoodie.datasource.write.reconcile.schema':'true',
'hoodie.table.cdc.enabled':'true',
}
inserts = inserts.withColumn("report_date", expr("CAST(report_date as
timestamp)"))
inserts.write.format("hudi"). \
options(**hudi_options). \
mode("overwrite"). \
save(basePath)
cdc_read_options = {
'hoodie.datasource.query.incremental.format': 'cdc',
'hoodie.datasource.query.type': 'incremental',
'hoodie.datasource.read.begin.instanttime': 0
}
df = spark.read.format("hudi").load(basePath)
df.show(10, False)
spark.read.format("hudi"). \
options(**cdc_read_options). \
load(basePath).show(10, False)
```
