记录一个因spark不是纯净版导致hive跑spark的insert，update语句报类找不到的问题

【背景说明】

我hive能正常启动，建表没问题，我建了一个student表，没问题，但执行了下面一条insert语句后报如下错误：

hive (default)> insert into table student values(1,'abc');
Query ID = atguigu_20240417184003_f9d459d7-1993-487f-8d5f-eafdb48d94c1
Total jobs = 1
Launching Job 1 out of 1
In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
  set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
  set mapreduce.job.reduces=<number>
Failed to monitor Job[-1] with exception 'java.lang.IllegalStateException(Connection to remote Spark driver was lost)' Last known state = SENT
Failed to execute spark task, with exception 'java.lang.IllegalStateException(RPC channel is closed.)'
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.spark.SparkTask. RPC channel is closed.

因为我是yarn跑的，所以去yarn看报错日志。

yarn报错日志如下：

它说是这个类找不到？！

【原因及解决】：其实就是我spark的包弄错了，应该是用纯净版的spark包。重新解压到module目录下，其他操作和spark原来的都一样。
