ambari 2.7.8 Hive on spark 配置問題解決
因為ambari默認(rèn)的引擎為tez拄轻，所以建議直接使用tez
ambari綁定的hive on spark 適配并不是特別好 記錄一下解決的問題
版本
Hadoop 3.1.1
Hive 3.1.0
Spark2 2.3.0
綜合解決
#解決hive 啟動使用spark引擎直接報錯 將spark包放到hive路徑下 使hive可以使用spark引擎

解決
- 如果任務(wù)已經(jīng)跑在yarn上 想辦法查看spark-history的日志 再進(jìn)一步排查
- 如果hive還無法跑在yarn上毛仪，查看ambari集成的服務(wù)的默認(rèn)日志路徑
/var/log/hive/..再進(jìn)一步排查

解決辦法 參考上一步
錯誤原因：spark2自帶的錯誤的版本的hive包 產(chǎn)生了jar包沖突
刪掉hdfs上的orc-core-1.4.4-nohive.jar即可（前提是已經(jīng)配置了hive-site配置了spark.yarn.jars）

case FAST 的代碼是有問題的，發(fā)現(xiàn)可以通過修改參數(shù) 可以通過修改配置不走FAST
set hive.mapjoin.optimized.hashtable=false;
查看ambari web的參數(shù) 發(fā)現(xiàn)了這個參數(shù)在web上有
備注是：hive.mapjoin.optimized.hashtable
Whether Hive should use memory-optimized hash table for MapJoin.Only works on Tez,
because memory-optimized hashtable cannot be serialized.
翻譯：hive.mapjoin.optimized.hashtable
Hive是否應(yīng)該為MapJoin使用內(nèi)存優(yōu)化的哈希表。僅適用于Tez，
因為內(nèi)存優(yōu)化的hashtable無法序列化冲泥。
是專門給tez引擎的，直接取消勾選壁涎，重啟hive即可
