Hi, We are on CDH3u3 .
- Himanish ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Hi, We have a business scenario wherein we need to perform lot of gets for each individual row from a Hbase table. To improve the performance we have used the batch facilities using HTable.batch(...) >From unit test case(run locally) ,the time taken for approx 120k gets was between 5-7 secs . But when we run the same piece of code through Map-Reduce (the batch get calls being made from the Mapper) the time take is between 20 - 30 secs for far less amount of gets ( between 1200 - 2000). Could somebody please explain why this could be happening from Map-Reduce ? Any suggestion on how to improve this scenario is really appreciated. -------------------------- Thanks & Regards Himanish -- Thanks & Regards Himanish
