incompatible with 0.5 for fixed types
[ https://issues.apache.org/jira/browse/HUDI-826?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Udit Mehrotra updated HUDI-826:
-------------------------------
Fix Version/s: (was: 0.9.0)
0.10.0
> Spark to avro schema in 0.6 incompatible with 0.5 for fixed types
> -----------------------------------------------------------------
>
> Key: HUDI-826
> URL: https://issues.apache.org/jira/browse/HUDI-826
> Project: Apache Hudi
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: Alexander Filipchik
> Priority: Major
> Fix For: 0.10.0
>
>
> Let's say we had some dataset created with SQL transformer using a query:
> {code:java}
> // select bla AS DECIMAL(20, 9)) bla
> {code}
> In 0.5 spark->avro converter (Databrics) would generate something like:
>
> {code:java}
> // {
> "name": "bla",
> "type": [
> "string",
> "null"
> ]
> },
> {code}
> in 0.6 (Spark):
>
>
> {code:java}
> // {
> "name": "bla",
> "type": [
> {
> "type": "fixed",
> "name": "order_subtotal",
> "namespace": "",
> "size": 16,
> "logicalType": "decimal",
> "precision": 38,
> "scale": 17
> }, "null"
> ]
> },
> {code}
> types are very different in that case. During the merge reader would fail with:
> {code:java}
