故障描述
hdp 3默认采用tez引擎,根据业务需求,需临时更换为spark引擎。
采用
set hive.execution.engine=spark;
set spark.executor.instances=40;
报错如下
Error while processing statement:Canot modly spark.executor.instances at runtime, t is not in list of params that are alowed to be modifed at runtime
故障分析
无
处理过程
hive 3开始,默认进行安全授权,防止运行时修改参数。把hive配置中hive.security.authorization.enabled关闭后再行测试即可。
建议/总结
无
