Use Configuration object instead of Properties in TraceBuilder
--------------------------------------------------------------
Key: MAPREDUCE-2152
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2152
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Ravi Gummadi
Currently, TraceBuilder has its own mapping of old and new mapreduce
configuration properties. This is fine till now because there are only few(3 or
4) configuration properties of interest.
But as we are planning to bring in more and more configuration properties into
the trace file(9 properties are needed for emulating distributed cache usage in
gridmix and about 5 properties are needed for emulating data compression in
gridmix jobs and few other properties like io.sort.mb, io.sort.factor which
should ideally be set for gridmix jobs), it is better to make TraceBuilder use
Configuration object. This avoids code duplication regarding mapping between
deprecated configration properties and current/new configuration properties.
