Project: Apache Hudi
Issue Type: Bug
Reporter: Alexey Kudinkin
Assignee: Alexey Kudinkin
Fix For: 0.13.0
Currently using `CustomKeyGenerator` with the partition-path config
\{hoodie.datasource.write.partitionpath.field=ts:timestamp} fails w/
{code:java}
Caused by: java.lang.RuntimeException: Failed to cast value `2022-05-11` to
`LongType` for partition column `ts_ms`

{code}
This occurs b/c SparkHoodieTableFileIndex produces incorrect partition schema
at XXX
where it properly handles only `TimestampBasedKeyGenerator`s but not the other
key-generators that might be changing the data-type of the partition-value as
compared to the source partition-column (in this case it has `ts` as a long in
the source table schema, but it produces partition-value as string)
