Intermittently unavailable: Maven library com.crealytics:spark-excel_2.12:3.5.0_0.20.3

[sudhakargen]

The issue is that the package com.crealytics:spark-excel_2.12:3.5.0_0.20.3 is intermittently unavailable i.e. most of the times excel import works and few times it fails with exception (org.apache.spark.SparkClassNotFoundException).

I have installed maven package com.crealytics:spark-excel_2.12:3.5.0_0.20.3 on a bricks cluster(14.2) with spark_version: "14.2.x-scala2.12" and "effective_spark_version": "14.2.x-photon-scala2.12". I'm using databricks-connect python library to import files from Azure blob storage from another application. Any help is appreciated.

Hi, Looks like the issue is source is not able to reach `https://spark.apache.org/third-party-projects.html` . Could you please try to download the package and install it locally? Also, is there any dependency error? Have you tried installing the package through normal libraries?

"Looks like the issue is source is not able to reach" - Can you please let me know what you mean by this.

Libraries installed on the databricks cluster are as below, I have a cluster with14.2 version on which I have installed maven library(com.crealytics:spark-excel_2.12:3.5.0_0.20.3). We auto-terminate the cluster after say X - minutes of inactivity (JFYI). 

Now the problem is when I try to import data from excel file I get this error intermittently i.e. not always. This was working always without any issues when I was using 13.2 version cluster. Since I have upgraded to 14.2 databricks cluster I'm seeing this error (org.apache.spark.SparkClassNotFoundException). Im using databricks-connect to import data from external sources.
