how do I install parckage(such as mmlspark) to CDH cluster without network access?

问题

由于中国难以连接到maven.org,您无法通过以下方式安装mmlspark

pyspark --packages com.microsoft.ml.spark:mmlspark_2.11:1.0.0-rc1 --repositories=https://mmlspark.azureedge.net/maven

出现了以下错误:

您尝试了手动安装,将包下载到Amazon EC2实例,然后复制到本地CDH集群路径 /opt/cloudera/parcels/CDH/lib/spark/jars/mmlspark_jars/,并设置了相应的配置。然而,即使jar被加载,仍然出现了import mmlspark时的ModuleNotFoundError错误。

最后,您尝试了另一种方法,将mmlspark.jar提取出来,压缩成.zip文件,然后放到HDFS中,并在pyspark中使用--py-files加载.zip文件,这样import mmlspark才成功。

接下来,您尝试了一些代码,但出现了错误:

Py4JJavaError                             Traceback (most recent call last)
...
java.util.NoSuchElementException: Param metric does not exist.
...

这个错误可能是因为mmlspark Python端无法加载jar文件引起的。如果您需要帮助解决此错误,请提供更多关于您的环境和配置的信息。

Because it is hard to connect maven.org in China , I can't not install mmlspark by

Try installation manually

I have an amazon ec2 instance , it can access the maven.org , I downloaded all packages and copy to local CDH cluster , path /opt/cloudera/parcels/CDH/lib/spark/jars/mmlspark_jars/ ,

And set config :

First
spark-defaults.conf:

如何在没有网络访问的情况下将包(例如mmlspark)安装到CDH集群?

But import mmlspark still ModuleNotFoundError: No module named 'mmlspark'

With some effort

I found: extract mmlspark.jar, zip mmlspark inside the folder and put to hdfs( hdfs://test/mmlspark.zip ), load this .zip in pyfiles (--py-files hdfs://test/mmlspark.zip ), Can make import mmlspark success .

I start a pyspark shell with jar dependencies and mmlspark.zip :

Here, I think this error is because mmlspark python port can not load the jar , which causes Py4JJavaError. But I have no idea, I have done everything I know .

Finally I got it around.
The key is pass .jar to pyFiles, this is very surprise me that python can read .jar .

bash:

pyspark \
--master yarn \
--conf spark.submit.pyFiles=hdfs://pupuxdc/user/spark/mmlspark_jars/…… .jar \
--conf spark.yarn.dist.jars=hdfs://pupuxdc/user/spark/mmlspark_jars/…… .jar

pyspark code:

spark_builder = (
    SparkSession
    .builder
    .config("spark.port.maxRetries", 100)
    .appName(app_name))
    
spark = spark_builder.getOrCreate()
jar_files = [...]
for i in jar_files:
    spark.sparkContext.addPyFile(i)

Notice, .config('spark.submit.pyFiles=hdfs://pupuxdc/user/spark/mmlspark_jars/…… .jar') doesn't take effect.

I tried comment, but I do not have enough reputation, so for those using HDP the same answer from Mithril applies.

Also, you are no required to upload the jar files to hdfs. I can achieve the same result reading the jar files from local dirs.

bash:

pyspark \
--master yarn \
--py-files /<path>/.jar,/<path>/.jar,/<path>/.jar... \
--jars /<path>/.jar,/<path>/.jar,/<path>/.jar...

It works with Jupyter Notebook, too. Just include following line just before stars the SparkSession.

os.environ['PYSPARK_SUBMIT_ARGS'] = '--py-files /<path>/.jar,/<path>/.jar,/<path>/.jar... --jars /<path>/.jar,/<path>/.jar,/<path>/.jar...'
