hive报错，

执行hive语句报下面错误

Exception in thread "Thread-150" java.lang.RuntimeException: Error while reading from task log url

习惯性的访问http://hadoop-client1:50060/tasklog?taskid=attempt_201508171753_0008_m_000000_2&start=-8193 ，居然是HTTP ERROR 400

所以要将这个地址改一下，将taskid改成attemptid

http://hadoop-client1:50060/tasklog?attemptid=attempt_201508171753_0008_m_000000_2&start=-8193

这样就能看见错误信息了
