sivabalan narayanan commented on HUDI-1842:
-------------------------------------------
I was just playing around. Just dumping my findings here.
I tried creating a table via spark shell as per quick start. And then executed
this command
create table hudi_cow1 (begin_lat double, begin_lon double, driver string,
end_lat double, end_lon double, fare double, partitionpath string, rider
string, ts bigint, uuid string) using hudi options(primaryKey = 'uuid',
precombineField = 'ts') partitioned by (partitionpath) location
'file:///tmp/hudi_cow/';
table name has to match the table name as per hoodie.properties.
Note: I created this table with latest master and so it had all the required
properties required for sql even though it was created with spark ds.
After this, I tried to insert records
insert into hudi_cow1 values(1.0, 2.0, "driver_1", 3.0, 4.0, 100.0, "rider_1",
12345, "ajsdfih23498q405qtahgkfsg", "americas/united_states/san_francisco/");
I see that for record key and partition path, respective field names are
prefixed to col values.
Result of select command.
// showing 2 rows. 1 row was inserted via spark-shell and another one(2nd row)
is inserted via spark-sql.

> [SQL] Spark Sql Support For The Exists Hoodie Table
> ---------------------------------------------------
>
> Key: HUDI-1842
> URL: https://issues.apache.org/jira/browse/HUDI-1842
> Project: Apache Hudi
> Issue Type: Sub-task
> Reporter: pengzhiwei
> Priority: Blocker
> Labels: release-blocker
> Fix For: 0.9.0
>
>
> In order to support spark sql for hoodie, we persist some table properties to
> the hoodie.properties. e.g. primaryKey, preCombineField, partition columns.
> For the exists hoodie tables, these properties are missing. We need do some
> code in UpgradeDowngrade to support spark sql for the exists tables.
