Alexey Kudinkin updated HUDI-5392:
----------------------------------
Description:
When writing Bootstrap file we’re using Spark writer that writes arrays in the
new format, while Hudi reads it in the old (Avro compatible) format:
{code:java}
// Old
optional group tip_history (LIST) {
repeated group array {
optional double amount;
optional binary currency (UTF8);
}
}
// new
optional group tip_history (LIST) {
repeated group list {
optional group element {
optional double amount;
optional binary currency (UTF8);
}
}
} {code}
To fix that we need to make sure that Bootstrap files are *always* read in a
new format (Spark default) unlike Hudi's Parquet files
We also need to fix TestDataSourceForBootstrap, as it currently doesn't
actually assert that the records are written correctly.
