大叔经验分享（84）spark sql中设置hive.exec.max.dynamic.partitions无效

spark 2.4

 

spark sql中执行

set hive.exec.max.dynamic.partitions=10000;

后再执行sql依然会报错：

org.apache.hadoop.hive.ql.metadata.HiveException:
Number of dynamic partitions created is 1001, which is more than 1000.
To solve this try to set hive.exec.max.dynamic.partitions to at least 1001.

这个参数hive.exec.max.dynamic.partitions的默认值是1000，修改没有生效，

 

原因如下：

`HiveClient` does not know new value 1001. There is no way to change the default value of `hive.exec.max.dynamic.partitions` of `HiveCilent` with `SET` command.

The root cause is that `hive` parameters are passed to `HiveClient` on creating. So, the workaround is to use `--hiveconf` when starting `spark-shell`.

 

解决方法是在启动spark-sql时设置hiveconf

spark-sql --hiveconf hive.exec.max.dynamic.partitions=10000
