--------------------------------
Summary: Parallel Container Launch of TaskRunnerLauncherImpl
Key: TAJO-51
URL: https://issues.apache.org/jira/browse/TAJO-51
Project: Tajo
Issue Type: Improvement
Components: master
Reporter: Hyunsik Choi
TaskRunnerLauncherImpl plays a role to launch remote containers via the proxy
of ContainerManager. This implementation sequentially launches containers, so
it may take a long time in large clusters. For example, it consumes about 5
seconds for starting 128 containers in our cluster, consisting of 32 nodes.
To relieve this time-consuming work, we can make this part parallel by using
ExecutorService.
