Hello all, I have setup my job on Amazon Elastic Map Reduce some how after reading the various links and some blogs. Now I am running my java code which has task in Hive and JDBC.
I have test my program on local machine (single cluster). It is executing well with no errors. But to increase the execution speed. Now I start running that program on Amazon EMR but my execution is too slow compare to single cluster machine. I am running my program with 2 Medium sized instance. Why is it so? Pls let me know about this. Thanks. -- Regards, Bhavesh Shah
