rbhartia opened a new issue #971: Setting "hoodie.parquet.max.file.size" to a value > 1 GB leads to no data being generated URL: https://github.com/apache/incubator-hudi/issues/971 Environment: EMR cluster version 5.27 using hudi-spark-bundle-0.5.1-SNAPSHOT.jar. "spark.executor.memory" is configured as 6018M. Running the following code, with "hoodie.parquet.max.file.size" to 2* 1024 * 1024 * 1024 (2GB) generates no data - ``` val inputDF = spark.read.format("parquet").load("s3://athena-examples-us-west-2/elb/parquet/year=2015/month=1/day=1/") inputDF.write .format("org.apache.hudi") .option("hoodie.parquet.max.file.size",String.valueOf(2*1024 * 1024 * 1024)) .option(DataSourceWriteOptions.RECORDKEY_FIELD_OPT_KEY, "request_ip") .option(DataSourceWriteOptions.PARTITIONPATH_FIELD_OPT_KEY, "request_verb") .option(HoodieWriteConfig.TABLE_NAME, "elb_logs_hudi_cow") .option(DataSourceWriteOptions.OPERATION_OPT_KEY, DataSourceWriteOptions.INSERT_OPERATION_OPT_VAL) .option(DataSourceWriteOptions.PRECOMBINE_FIELD_OPT_KEY, "request_timestamp") .mode(SaveMode.Overwrite) .save("s3://my-bucket/prefix") ``` All the stages and tasks complete successfully with no OOM or error messages being printed in the log. There is a commit files in .hoodie folder, but that is also empty. Changing the option "hoodie.parquet.max.file.size" to 1024 * 1024 * 1024 (1GB) makes everything work as expected.
