Davies Liu fc29b896da [SPARK-15392][SQL] fix default value of size estimation of logical plan ## What changes were proposed in this pull request? We use autoBroadcastJoinThreshold + 1L as the default value of size estimation, that is not good in 2.0, because we will calculate the size based on size of schema, then the estimation could be less than autoBroadcastJoinThreshold if you have an SELECT on top of an DataFrame created from RDD. This PR change the default value to Long.MaxValue. ## How was this patch tested? Added regression tests. Author: Davies Liu <davies@databricks.com> Closes #13179 from davies/fix_default_size.		2016-05-18 15:45:59 -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)

└── 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
