hive報錯

執行hive語句報下面錯誤

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

習慣性的訪問http://hadoop-client1:50060/tasklog?taskid=attempt_201508171753_0008_m_000000_2&start=-8193 ，居然是HTTP ERROR 400

所以要將這個地址改一下，將taskid改成attemptid

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

這樣就能看見錯誤信息了
