Cloudera Manager cannot find Spark2 parcel

[ Edited ]

I have cloudera Manager 5.12.1 and After having installed the CSD following the first steps of this guide: https://www.cloudera.com/documentation/spark2/latest/topics/spark2_installing.html

 

but after restarting the Cloudera Manager, even if it automatically added the remote parcel repository URL (effect from the installation of the CSD) . I cannot find the new parcel in order to download it.

I digged into the logs and I found this warning

 

4:18:57.328 PM 	WARN 	ReadWriteDatabaseTaskCallable

java.lang.NullPointerException

maybe it cannot download the parcels? why? I have no firewall or proxy activated.

 

 

I have CENTOS7

There's a parcel from https://archive.cloudera.com/sqoop-connectors/parcels/latest/ (which is included by default) that seems to give problems. Try to exclude it.

Re: Cloudera Manager cannot find Spark2 parcel

I didn't get why is this a problem for Cloudera. But excluding it, it actually worked!
