* Optimize your MapReduce task functionality * establish your
Hadoop cluster's weaknesses * music your MapReduce configuration
MapReduce is the distribution method that the Hadoop MapReduce
engine makes use of to distribute paintings round a cluster by means of working
parallel on smaller information units. it truly is important in a variety of
applications, together with allotted pattern-based searching
distributed sorting, net link-graph reversal, term-vector per
host, net entry log stats, inverted index building, document
clustering, laptop studying, and statistical machine
This e-book introduces you to complicated MapReduce suggestions and
teaches you every thing from choosing the criteria that affect
MapReduce activity functionality to tuning the MapReduce configuration
Based on real-world adventure, this ebook can help you to fully
utilize your cluster's node assets to run MapReduce jobs
This booklet info the Hadoop MapReduce task performance
optimization procedure. via a few transparent and practical
steps, it's going to assist you to completely make the most of your cluster's node

MapReduce functionality, you may be given an summary of Hadoop
metrics and a number of other functionality tracking instruments. extra on, you
will discover functionality counters that assist you determine resource
bottlenecks, payment cluster overall healthiness, and dimension your Hadoop cluster
You also will find out about optimizing map and decrease initiatives by
using Combiners and compression
The e-book ends with most sensible practices and suggestions on how to
use your Hadoop cluster optimally
What you are going to research from this book
* know about the criteria that have an effect on MapReduce functionality *
Utilize the Hadoop MapReduce functionality counters to identify
resource bottlenecks * dimension your Hadoop cluster's nodes * Set the
number of mappers and reducers thoroughly * Optimize mapper and
reducer activity throughput and code measurement utilizing compression and
Combiners * comprehend some of the tuning houses and best
practices to optimize clusters
