[jira] [Created] (HUDI-4784) Full-record bootstrap does not generate correct partition path
Ethan Guo created HUDI-4784:
-------------------------------
Summary: Full-record bootstrap does not generate correct partition path
Key: HUDI-4784
URL: https://issues.apache.org/jira/browse/HUDI-4784
Project: Apache Hudi
Issue Type: Bug
Reporter: Ethan Guo
The source partitioned parquet table is structured based on year/month/day. The bootstrap operation performs both metadata_only and full_record bootstrap using Spark datasource. The partitions with full_record bootstrap do not have the correct partition path generated in the target Hudi table.
{code:java}
val srcPath = "<>/bootstrap-testing/partitioned-parquet-table-date"
val basePath = "<>/bootstrap-testing/bootstrap-hudi-table-2"
val bootstrapDF = spark.emptyDataFrame
bootstrapDF.write
.format("hudi")
.option(HoodieWriteConfig.TABLE_NAME, "hoodie_test")
.option(DataSourceWriteOptions.OPERATION_OPT_KEY, DataSourceWriteOptions.BOOTSTRAP_OPERATION_OPT_VAL)
