hive tracker

Hive tracker指的是Hive作业跟踪器，它用于跟踪Hive作业的执行情况和状态。根据引用中提供的信息，可以看出，设置`mapred.job.tracker`参数为`impala11:8021`，其中`impala11:8021`是Hadoop JobTracker的主机名和端口。这意味着Hive作业会将它们的信息发送给该主机和端口，以便进行跟踪和监控。引用中提到，默认情况下，每个tasktracker同时运行的map任务数为2。这可能对Hive作业的并发性和性能有一定影响。如果希望调整这个参数，可以通过设置`mapred.tasktracker.map.tasks.maximum`来实现。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
