通过在 Jupyter Notebook 中不起作用的引导操作在 EMR 上安装包

Question

I have an EMR cluster using EMR-6.3.1. I am using the Python3 Kernel.

I have a very simple bootstrap script in S3:

#!/bin/bash

sudo python3 -m pip install Cython==0.29.4 boto==2.49.0 boto3==1.18.50 numpy==1.19.5 pandas==1.3.2 pyarrow==5.0.0

These are the bootstrap logs

+ sudo python3 -m pip install Cython==0.29.4 boto==2.49.0 boto3==1.18.50 numpy==1.19.5 pandas==1.3.2 pyarrow==5.0.0

From a notebook, importing pandas and seeing the wrong version - 1.2.3. Further, I see pyarrow fails to import.

I've printed the import path of pandas, which python version is run, and sys.path.

import os
import pandas
import sys
print(sys.path)
print(pandas.__version__)
print(os.path.abspath(pandas.__file__))
print(os.popen('echo $PYTHONPATH').read())
print(os.popen('which python3').read())

# sys.path.append('/usr/local/lib64/python3.7/site-packages') # if I add this, pyarrow can import
import pyarrow

['/', '/emr/notebook-env/lib/python37.zip', '/emr/notebook-env/lib/python3.7', '/emr/notebook-env/lib/python3.7/lib-dynload', '', '/emr/notebook-env/lib/python3.7/site-packages', '/emr/notebook-env/lib/python3.7/site-packages/awseditorssparkmonitoringwidget-1.0-py3.7.egg', '/emr/notebook-env/lib/python3.7/site-packages/IPython/extensions', '/home/emr-notebook/.ipython']
1.2.3
/emr/notebook-env/lib/python3.7/site-packages/pandas/__init__.py


/usr/bin/python3

     10 # sys.path.append('/usr/local/lib64/python3.7/site-packages') # if I add this, pyarrow can import
---> 11 import pyarrow

ModuleNotFoundError: No module named 'pyarrow'

I found I can import pyarrow if I add /usr/local/lib64/python3.7/site-packages to sys.path. This seems like am improvement, but still the wrong version of pandas is imported.

I've tried:

• SSH'ing into the master node and mucking with the configuration.
• sudo python3 -m pip install --user...
• export PYTHONPATH=/usr/local/lib64/python3.7/site-packages && sudo python3 -m pip install...
• sudo pip3 install --upgrade setuptools && sudo python3 -m pip install...
• Using a pyspark kernel and running sc.install_pypi_package("pandas==1.3.2")

Any help is appreciated. Thank you.

The bootstrap configuration on EMR is not the last step before the cluster is WAITING and EMR Steps start running.

On my emr cluster I found that at the least these packages were logged as installed after the bootstrap configuration ran. I was having issues with numpy not upgrading.

Python packages installed post bootstrap

2022-12-10 00:10:28,250 INFO main: Took 1 minute, 3 seconds and 451 milliseconds to install packages:

[emr-scripts, emr-s3-select, aws-sagemaker-spark-sdk, python27-numpy, python27-sagemaker_pyspark, python37-numpy, python37-sagemaker_pyspark, emr-ddb, hadoop-yarn-nodemanager, docker, hadoop-yarn, spark-yarn-shuffle, bigtop-utils, cloudwatch-sink, hadoop, hadoop-lzo, emr-goodies, emrfs, hadoop-mapreduce, hadoop-hdfs, R-core, aws-hm-client, emr-kinesis, hadoop-hdfs-datanode, spark-datanucleus]

A work around to in your first cluster step to add the installition

...
Steps: [

        {
            'Name': 'Install Pandas',
            "ActionOnFailure": "CONTINUE",
            "HadoopJarStep": {
                "Jar":
                "s3://us-east-1.elasticmapreduce/libs/script-runner/script-runner.jar",
                "Args": [
                    "s3://bucket/prefix/install_packages.sh"
                ]
            }
        },
]

Or if you want to use command-runner

{
            "Name": "Install Pandas",
            "ActionOnFailure": "CONTINUE",
            "HadoopJarStep": {
                "Jar": "command-runner.jar",
                "Args": [
                    "bash",
                    "-c",
                    " aws s3 cp s3://bucket/prefix/install.sh .; chmod +x install.sh; ./install.sh; rm install_pandas.sh "
                ]
            }
        }

In my example my install.sh file looks like

#!/bin/bash
set -x

sudo pip3 freeze # for debugging to view the previous package versions
sudo pip3 uninstall numpy -y -v
sudo yum install python3-devel -y
sudo pip3 install boto3==1.26.26 -v
sudo pip3 install numpy==1.21.6 -v
sudo pip3 install pandas==1.3.5 -v
sudo pip3 freeze # for debugging to view the post-install package versions
