Hadoop from space - processing bits
12
Hadoop is bad at:
๏Calling native C code or libraries at scale
๏Scientific computing is immature in Java
HadoopWorld 2011
Hadoop from space - processing bits
13
Standard Java Hadoop
๏Hadoop knows where data stored
๏Jobs efficiently scheduled close to data
๏Throughput optimized

Hadoop from space - processing bits
14
Hadoop Pipes & Streaming
๏Hadoop schedules jobs without regard to
the data required by the job
๏Native code reads data across the network
๏Drives up network costs and drives down
throughput
