Seattle Hadoop Distributing Computing User Meeting
==================================================
Bringing Hadoopists Together On the 3rd
Thursday of the Month
We focus predominately on distributed data
processing using a map reduce style. The meetings
are open to all and free of charge.
When: Thursday April 21st, 7:00 pm room, 7:15 start - 8:45
Where: University Heights Community Center, Room 110
Outline for April 21st:
Serialization Super Special!
We will cover Avro the up and coming cross platform
data serialization and RPC mechanism targeted at
Hadoop.
The use of Avro both simplifies and accelerates the
Hadoop workflow by making the inputs and the outputs
to your mappers and reducers more tractable. By
coaelescing many small files into Avro records the
job processing time becomes shorter.
The current outline:
Avro Schema definition and the design of quality
long term data structures.
Examples of reading and writing Avro files in
Java, Python and C
Writing Mapreduce jobs that operate over Avro
files using the AvroMapper and AvroReducer.
