Set the index of gdp_data to the values in column state_code

Sure, here's the code to set the index of `gdp_data` to the values in column `state_code`:

gdp_data.set_index('state_code', inplace=True)

This will modify the `gdp_data` DataFrame so that the `state_code` column becomes the new index.

以下是什么意思Set the index of gdp_data to the values in column state_code

这个问题的意思是要求把 `gdp_data` 的索引（行标签）设置为 `state_code` 这一列的值。也就是把 `state_code` 这一列的值作为每一行的标识符，方便后续的数据处理和分析。在 Pandas 中，可以使用 `set_index` 方法来设置 DataFrame 的索引。具体实现可以参考我之前给出的代码。

please set $hadoop_mapred_home to the root of your hadoop mapreduce installa

tion.

To set the `hadoop_mapred_home` environment variable to the root of your Hadoop MapReduce installation, you can follow these steps:

1. Determine the location of your Hadoop MapReduce installation. This could be `/usr/local/hadoop` or another directory where Hadoop is installed.

2. Set the `hadoop_mapred_home` environment variable to the root of your Hadoop MapReduce installation by running the following command in your terminal:

   export hadoop_mapred_home=/path/to/hadoop

Replace `/path/to/hadoop` with the actual path to your Hadoop MapReduce installation.

3. To make this environment variable persistent across terminal sessions, you can add the above command to your shell profile file (e.g. `~/.bashrc` for Bash shell).

   echo 'export hadoop_mapred_home=/path/to/hadoop' >> ~/.bashrc
   source ~/.bashrc

Replace `/path/to/hadoop` with the actual path to your Hadoop MapReduce installation.
