Amazon EMR pip install in bootstrap actions runs OK but has no effect

Asked 2020-Dec-07 at 12:49

In Amazon EMR, I am using the following script as a custom bootstrap action to install python packages. The script runs OK (checked the logs, packages installed successfully) but when I open a notebook in Jupyter Lab, I cannot import any of them. If I open a terminal in JupyterLab and run pip list or pip3 list, none of my packages is there. Even if I go to / and run find . -name mleap for instance, it does not exist.

Something I have noticed is that on the master node, I am getting all the time an error saying bootstrap action 2 has failed (there is no second action, only one). According to this, it is a rare error which I get in all my clusters. However, my cluster eventually gets created and I can use it.

My script is called aws-emr-bootstrap-actions.sh

The PYSPARK, Python interpreter that Spark is using, is different than the one to which the OP was installing the modules (as confirmed in comments).

I found the problem and a workaround.

It is not possible anymore to do random writes with Databricks as explained here: https://docs.databricks.com/data/databricks-file-system.html?_ga=2.197884399.1151871582.1592826411-509486897.1589442523#local-file-apis

A workaround is to write the zip file in the local filesystem and then copy it into DBFS. So:

Serialize your model in a Pipeline using "init=True" saving it in a local dir
Copy it to your datalake by using "dbutils.fs.cp(source, destination)"

dbutils.fs.cp(source, destination)

QUESTION

How to use MLeap DenseTensor in Java

Asked 2020-Jun-06 at 15:37

I am using MLeap to run a Pyspark logistic regression model in a java program. Once I run the pipeline I am able to get a DefaultLeapFrame object with one row Stream(Row(1.3,12,3.6,DenseTensor([D@538613b3,List(2)),1.0), ?).

But I am not sure how to actually inspect the DenseTensor object. When I use getTensor(3) on this row I get an object. I am not familiar with Scala but that seems to be how this is meant to be interacted with. In Java how can I get the values within this DenseVector?

Here is roughly what I am doing. I'm guessing using Object is not right for the type. . .

So the MLeap documentation for the Java DSL is not so good but I was able to look over some unit tests (link) that pointed me to the right thing to use. In case anyone else is interested, this is what I did.

It looks like I just needed to restart R. I had other issues with loading the mleap library for another version of the spark (3.0.0-review2), and I mixed it up.
