Thanks in advance 回答1: Figured out the answer to my own question. Serialization The code snippet below illustrates how

问题 I'm trying to get spark to read uncompressed thrift files from s3. So far it has not been working. data is loaded in s3 as uncompressed thrift files. The source is AWS Kinesis Firehose. I have a tool that deserializes files with no problem, so I know that thrift serialization/deserialization works. in spark, im using newAPIHadoopFile using elephantbird's LzoThriftBlockInputFormat, I am able to successfully read lzo-compressed thrift files I can't figure out what InputFormat should I use to

问题 Does the .thrift file reside in the Server side or the client side of the application? What is actual purpose of .thrift file in an Apache Thrift based application? Is it only used for generating minimal source codes for the application, or, does it have any other use? Can't I just write client-server codes myself without taking the help of .thrift file? 回答1: The *.thrift file is an IDL file, where IDL stands for Interface description language. The main purpose of this file is to generate the

问题 I am trying to write a PHP client for a Thrift server written in C. I am following the tutorial given at http://chanian.com/2010/05/13/thrift-tutorial-a-php-client/. I am very new to PHP and, I suspect, am missing some of the language fundamentals. The code in question is: <?php // Setup the path to the thrift library folder $GLOBALS['THRIFT_ROOT'] = 'Thrift'; // Load up all the thrift stuff require_once $GLOBALS['THRIFT_ROOT'].'/Thrift.php'; require_once $GLOBALS['THRIFT_ROOT'].'/protocol
