Subject [jira] Created: (MAPREDUCE-2152) Use Configuration object instead of Properties in TraceBuilder
Date Tue, 26 Oct 2010 06:01:20 GMT
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.
