Subject Re: Reading and writing Thrift data from MapReduce
Date Wed, 03 Sep 2008 04:37:28 GMT
Hey Juho,

You should check out Hive
(https://issues.apache.org/jira/browse/HADOOP-3601), which was just
committed to the Hadoop trunk today. It's what we use at Facebook to
query our collection of Thrift-serialized logfiles. Inside of the Hive
code, you'll find a pure-Java (using JavaCC) parser for
Thrift-serialized data structures.
