在hive中创建动态分区,将数据导入的过程中,出现的问题: 数据导入失败

FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
这个问题主要原因就是动态分区的数量没有达到要求,应该分区的数量设置多一些
Your Hive job tried to create too many dynamic partitions on a node, exceeding the current limits. The number of dynamic partitions is controlled by the settings forhive.exec.max.dynamic.partitions and hive.exec.max.dynamic.partitions.pernode. The default is 100 dynamic partitions on a single node, with a limit of 1000 overall.
设置一下:
SET hive.exec.dynamic.partition=true;
SET hive.exec.max.dynamic.partitions=2048;
SET hive.exec.max.dynamic.partitions.pernode=256;
完美解决:



本文解决在Hive中使用动态分区导入数据时遇到的执行错误问题,通过调整hive.exec.max.dynamic.partitions和hive.exec.max.dynamic.partitions.pernode参数的值,成功解决了因动态分区数量过多导致的数据导入失败。
