[GitHub] [iceberg] duanmeng opened a new pull request #1329: Support read data from iceberg table created by SparkSQL using hive
duanmeng opened a new pull request #1329:
URL: https://github.com/apache/iceberg/pull/1329
This PR implements:
- Add default Inputformat/Outputformat/serde (HiveIcebergInputForma,HiveIcebergOutputForma,HiveIcebergSerD) when creating iceberg table using SparkSQL.
- Add Hive Runtime to support read data from hive external table by adding jar in hive.
A hive external table would be created when create a iceberg table in SparkSQL, but its default Inputformat/Outputformat/serde is FileInputFormat/FileOutputFormat/LazySimpleSer, we can't read data from this external table. With this pr we can read data from the external table in hive (add jar and set mapreduce.input.fileinputformat.input.dir.recursive=true).

@duanmeng, sorry I didn't see this PR sooner. I think you would probably be interested in other PRs that have recently implemented functionality that is similar:
* #1267 added an iceberg-hive-runtime Jar with Iceberg dependencies bundled in
* #1505 makes tables readable in Hive when created in Spark, if the table or environment has a flag set
Please have a look at those and see if they do everything you need.
I'll close this PR since it overlaps the others, but feel free to open a new one if you have anything else to fix. Ping me and I'll take a look at future PRs.
