Data Discovery + Access Control + Encryption
If you are planning to migrate analytical workloads from on-prem to the public cloud then you must read this article. What I have encountered in the last 9 months is that organizations moving their data to the cloud not only struggle with ETL but also with an end to end data protection process which is comprised of Auto Data Discovery, Access Control, and Encryption.
What does Auto Data Discovery mean?
The goal of ETL jobs is to land data at the storage layer which can be ADLS, S3, GCS, or any of the traditional databases like Oracle, SQL server, or in case of cloud Aurora, RDS, Big Query, Snowflake and Databricks, etc. …

[root@xx ~]# cat /root/hostname.sh
I did try the following but no luck
type hostname >/dev/null 2>&1 || \
if [ -n “$1” ]; then
printf — “%s” “$1” > /proc/sys/kernel/hostname
if hname=$(getarg hostname=); then

Power BI is a collection of software services, apps, and connectors that work together to turn your unrelated sources of data into coherent, visually immersive, and interactive insights. Your data may be an Excel spreadsheet or a collection of cloud-based and on-premises hybrid data warehouses. Power BI lets you easily connect to your data sources, visualize and discover what’s important, and share that with anyone or everyone you want. Source
This article explains the integration of PowerBI with Databricks and how fine-grained access control take effect which is having table, column, and row-level access controls.
Let’s connect to Spark data…
This is a basic demo of how my life is so easier by using one platform to secure access for various data services like HDFS, Hive, AWS, EMR Hive, Databricks.
Looking forward to getting your feedback.
Qubole is a cloud-native data analytics platform that supports a number of enterprise-grade data processing engines such as Apache Spark, Presto, Hive, Quantum, Airflow, and more. It is used by companies like Expedia, Under Armour and Adobe.
As its popularity grows, more and more users from different departments with different roles across the enterprise are accessing data stored in Qubole. This increases the need for robust data access governance capabilities to comply with regulations like GDPR and CCPA.
Privacera, based on Apache Ranger, enables IT and data platform teams to automatically discover and classify sensitive data, define and enforce access control policies to that data, and monitor activity and report for compliance. …
Steps to install ambari server
[root@ip-172–31–41–233 ~]# cd ~/.ssh/
[root@ip-172–31–41–233 .ssh]# ls
authorized_keys id_rsa id_rsa.pub
[root@ip-172–31–41–233 .ssh]# cat id_rsa
You would need the above entry for the following:
[root@ip-172–31–41–233 ~]# ambari-server setup — jdbc-db=mysql — jdbc-driver=/usr/share/java/mysql-connector-java.jar
Using python /usr/bin/python
Copying /usr/share/java/mysql-connector-java.jar to /var/lib/ambari-server/resources/mysql-connector-java.jar
If you are updating existing jdbc driver jar for mysql with mysql-connector-java.jar. Please remove the old driver jar, from all hosts. Restarting services that need the driver, will automatically copy the new jar to the hosts.
JDBC driver was successfully initialized.
Ambari Server ‘setup’ completed successfully.

A Jupyter notebook is a web-based application used to create and share documents that contain both live code and rich text elements. It is popular with data scientists who use Jupyter notebooks for a number of use case including machine learning, statistical modeling, and data visualizations. One reason for Jupyter’s popularity is that it is language agnostic. Data scientists can run jobs in Jupyter notebooks using the language of their choice, such as PySpark and Scala.
Data scientists at Netflix, for example, use Jupyter notebooks to analyze and better understand user behavior and to develop new models to improve the user experience, as well as to share the results of their analysis and collaborate with colleagues. …
