kandi X-RAY | initialization-actions Summary
When creating a Dataproc cluster, you can specify initialization actions in executables and/or scripts that Dataproc will run on all nodes in your Dataproc cluster immediately after the cluster is set up. Initialization actions often set up job dependencies, such as installing Python packages, so that jobs can be submitted to the cluster without having to install dependencies when the jobs are run.

QUESTION
I'm creating a Dataproc cluster, and it is timing out when i'm adding the connectors.sh in the initialization actions.
here is the command & error
...ANSWER
Answered 2022-Feb-01 at 20:01It seems you are using an old version of the init action script. Based on the documentation from the Dataproc GitHub repo, you can set the version of the Hadoop GCS connector without the script in the following manner:

We use to spin cluster with below configurations. It used to run fine till last week but now failing with error ERROR: Failed cleaning build dir for libcst Failed to build libcst ERROR: Could not build wheels for libcst which use PEP 517 and cannot be installed directly
ANSWER
Answered 2022-Jan-19 at 21:50Seems you need to upgrade pip
, see this question.
But there can be multiple pip
s in a Dataproc cluster, you need to choose the right one.
For init actions, at cluster creation time,
/opt/conda/default
is a symbolic link to either/opt/conda/miniconda3
or/opt/conda/anaconda
, depending on which Conda env you choose, the default is Miniconda3, but in your case it is Anaconda. So you can run either/opt/conda/default/bin/pip install --upgrade pip
or/opt/conda/anaconda/bin/pip install --upgrade pip
.For custom images, at image creation time, you want to use the explicit full path,
/opt/conda/anaconda/bin/pip install --upgrade pip
for Anaconda, or/opt/conda/miniconda3/bin/pip install --upgrade pip
for Miniconda3.
So, you can simply use /opt/conda/anaconda/bin/pip install --upgrade pip
for both init actions and custom images.

QUESTION
I am trying to create a dataproc cluster that will connect dataproc to pubsub. I need to add multiple jars on cluster creation in the spark.jars flag
...ANSWER
Answered 2021-Nov-27 at 22:40The answer you linked is the correct way to do it: How can I include additional jars when starting a Google DataProc cluster to use with Jupyter notebooks?
If you also post the command you tried with the escaping syntax and the resulting error message then others could more easily verify what you did wrong. It looks like you're specifying an additional spark property in addition to your list of jars spark:spark.driver.memory=3000m
, and tried to just space-separate that from your jars flag, which isn't allowed.
Per the linked result, you'd need to use the newly assigned separator character to separate the second spark property:
QUESTION
I'm trying to run my application using Livy that resides inside GCP Dataproc but I'm getting this: "Caused by: java.lang.ClassNotFoundException: bigquery.DefaultSource"
I'm able to run hadoop fs -ls gs://xxxx inside Dataproc and I checked if Spark is pointing to the right location in order to find gcs-connector.jar and that's ok too.
I included Livy in Dataproc using initialization (https://github.com/GoogleCloudDataproc/initialization-actions/blob/master/livy/)
How can I include bigquery-connector in Livy's classpath? Could you help me, please? Thank you all!
...ANSWER
Answered 2021-Jul-02 at 18:48It looks like your application is depending on the BigQuery connector, not the GCS connector (bigquery.DefaultSource
).
The GCS connector should always be included in the HADOOP classpath by default, but you will have to manually add the BigQuery connector jar to your application.
Assuming this is a Spark application, you can set the Spark jar property to pull in the bigquery connector jar from GCS at runtime: spark.jars='gs://spark-lib/bigquery/spark-bigquery-latest_2.12.jar'
For more installation options, see https://github.com/GoogleCloudDataproc/spark-bigquery-connector/blob/master/README.md
QUESTION
- OS type and version: 1.5.29-debian10
- Python version: 3.7
google-cloud-bigquery
version: 2.8.0
I'm provisioning a dataproc cluster which gets the data from BigQuery into a pandas dataframe. As my data is growing I was looking to boost the performance and heard about using the BigQuery storage client.
I had the same problem in the past and this was solved by setting the google-cloud-bigquery to version 1.26.1. If I use that version I get the following message.
...ANSWER
Answered 2021-Feb-15 at 14:42Dataproc installs by default pyarrow 0.15.0 while the bigquery-storage-api needs a more recent version. Manually setting pyarrow to 3.0.0 at install solved the issue. That being said, PySpark has a compability setting for Pyarrow >= 0.15.0 https://spark.apache.org/docs/3.0.0-preview/sql-pyspark-pandas-with-arrow.html#apache-arrow-in-spark I've taken a look at the release notes of dataproc and this env variable is set as default since May 2020.
