Hive执行异常记录

Hive执行异常

(1)执行报错

如果是mr报错，那么就先看是否缺少了HADOOP_CONF_DIR
并检查hadoop-mapreduce-client-core-2.6.0,及hadoop-mapreduce-client-common-2.6.0.jar是否正确添加

若tez报错，查看是否在hive-site.xml中添加了hive-execution-engine，value为tez.
并且执行报错return code 12855时可以尝试使用如下参数进行配置:

set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
set hive.tez.input.format=org.apache.hadoop.hive.ql.io.CombineHiveInputFormat;
set hive.vectorized.execution.reduce.enabled;
set hive.vectorized.execution.reduce.enabled=false;
