Hadoop MySQL database access
Hi All, I wrote a map reduce program to fetch data from MySQL and process the data(word count). The program executes successfully . But I noticed that the reduce task starts after finishing the map task only . Is there any way to run the map and reduce in parallel. The program fetches data from MySQL and writes the processed output to hdfs. I am using hadoop in pseduo-distributed mode . -- ** JAGANADH G http://jaganadhg.in *ILUGCBE* http://ilugcbe.org.in
