1）執行hive cli客戶端時報錯：

Mkdirs failed to create /tmp/hadoop-test/hadoop-unjar15513

    解決辦法：a）清空/tmp目錄；b）修改hive的臨時目錄

2）hive提交的作業始終是map 0% red 0%的狀態：

    作業圖示如下：

   發現該job分配的map數為零，最初還以為是jobtracker的問題（因為剛上了fair scheduler，且恰巧昨天該job執行時，jobtracker也丟擲了異常），但是今天覆現時，發現其他的mapred job都能夠正常執行，所以在仔細查看了日誌後發現：

2011-11-17 10:17:36,071 INFO org.apache.hadoop.mapred.JobInProgress: Input size for job job_201111170937_0037 = 0. Number of splits = 0
2011-11-17 10:17:36,071 INFO org.apache.hadoop.mapred.JobInProgress: Job job_201111170937_0037 initialized successfully with 0 map tasks and 1 reduce tasks.

   3）在安裝新的hive服務時，必須要在hosts檔案中新增hadoop叢集伺服器的ip hostname資訊，且還需要新增本機的ip hostname資訊，否則會丟擲以下錯誤：

    5）hive檢視hadoop配置：

set -v 可得到所有環境變數。如果沒有-v引數，只顯示與hadoop不同的配置。
