0019 To avoid code generation during build time, Java code generated from testing Thrift schema and Avro IDL are also checked in.
0020
0021 When updating the testing Thrift schema and Avro IDL, please run `gen-avro.sh` and `gen-thrift.sh` accordingly to update generated Java code.
0022
0023 ## Prerequisites
0024
0025 Please ensure `avro-tools` and `thrift` are installed. You may install these two on Mac OS X via:
