Kunal Khamar 3783539d7a [SPARK-19873][SS] Record num shuffle partitions in offset log and enforce in next batch. ## What changes were proposed in this pull request? If the user changes the shuffle partition number between batches, Streaming aggregation will fail. Here are some possible cases: - Change "spark.sql.shuffle.partitions" - Use "repartition" and change the partition number in codes - RangePartitioner doesn't generate deterministic partitions. Right now it's safe as we disallow sort before aggregation. Not sure if we will add some operators using RangePartitioner in future. ## How was this patch tested? - Unit tests - Manual tests - forward compatibility tested by using the new `OffsetSeqMetadata` json with Spark v2.1.0 Author: Kunal Khamar <kkhamar@outlook.com> Closes #17216 from kunalkhamar/num-partitions.		2017-03-17 16:16:22 -07:00

Notes for Parquet compatibility tests

The following directories and files are used for Parquet compatibility tests:

.
├── README.md                   # This file
├── avro
│   ├── *.avdl                  # Testing Avro IDL(s)
│   └── *.avpr                  # !! NO TOUCH !! Protocol files generated from Avro IDL(s)
├── gen-java                    # !! NO TOUCH !! Generated Java code
├── scripts
│   ├── gen-avro.sh             # Script used to generate Java code for Avro

└── thrift
    └── *.thrift                # Testing Thrift schema(s)

To avoid code generation during build time, Java code generated from testing Thrift schema and Avro IDL are also checked in.

When updating the testing Thrift schema and Avro IDL, please run gen-avro.sh and gen-thrift.sh accordingly to update generated Java code.

Prerequisites

Please ensure avro-tools and thrift are installed. You may install these two on Mac OS X via:

$ brew install thrift avro-tools
