Hello Team,
I am having issues installing the latest version of Apache Lens . Thought I
would reach out since I have spent some time with fixing it ( and still
struggling).
Again, I might be missing something fundamental and I am sorry for a the
longish email.
Main use case - We are trying to evaluate Apache Lens for a customer who is
traditionally has OLAP experience and uses SQL Server Analysis Services
across the enterprise. We wanted to show them something similar in Hadoop
world where we provide an interface to the business users on an existing
Hadoop based data lake with close to around 5 TB of data. We would be using
Apache Lens in conjunction with apache zeppelin.
1. I have Hortonworks 2.3 in a 10 node cluster ( Evaluation Purpose with
scaled down data )
2. CentOS 7.X installation
3. Downloaded and unzipped the installables
- wget
http://www.eu.apache.org/dist//lens/2.3-beta/apache-lens-2.3.0-beta-bin.tar.gz
- tar zxvf apache-lens-2.3.0-beta-bin.tar.gz
4. Considering Hadoop and Hive are already installed throught
Hortonworks, set the variables to
- export HADOOP_HOME=/usr/hdp/current/hadoop-client;
- export HIVE_HOME=/usr/hdp/current/hive-client;
5. Configured lens-env.sh [image: Inline image 1]
6. Started Lens server [image: Inline image 2]
7. The log fine shows me the below error.

Not sure what is the mistake I am doing.
