Hi,   Im happy to set up a separate post, but was hoping you could pick this up here. Im having a similar problem with Spark and Hue on CDM.   I have a running CDM 5.7.1 cluster on Ubuntu 14.04, with all services working fine (apart from spark and impala).   It apears that the spark hostory servers and gateways are installed, but I cant activate Spark in Standalone or Spark on Yarn. In the parcels section I am getting errors across a number of services:   Error for parcel SPARK-0.9.0-1.cdh4.6.0.p0.98-trusty : Parcel not available for OS Distribution UBUNTU_TRUSTY. Error for parcel SOLR-1.3.0-1.cdh4.5.0.p0.9-trusty : Parcel not available for OS Distribution UBUNTU_TRUSTY. Error for parcel IMPALA-2.1.0-1.impala2.0.0.p0.1995-trusty : Parcel not available for OS Distribution UBUNTU_TRUSTY. Error for parcel ACCUMULO-1.4.4-1.cdh4.5.0.p0.65-trusty : Parcel not available for OS Distribution UBUNTU_TRUSTY. Having checked, this appears to mean that there isnt a Ubuntu Trusty version of the above parcels.   Can you confirm if this is the case.   If so, can I install the components via apt-get:   sudo apt-get install spark-core spark-master spark-worker spark-history-server spark-python as described in this link for CDM 5.4.x:   http://www.cloudera.com/documentation/enterprise/5-4-x/topics/cdh_ig_spark_install.html   Any guidance on this would be appreciated.   After installing spark, I'd like to activate the Hue Spark Notebook, but can see that in Hue app_blacklist is set to:   app_blacklist ['spark', 'zookeeper', 'security']   I have removed spark and zookeeper from the app_blacklist leaving 'security' and have restarted the Hue service, and refreshed Hue web UI, I can see only 'security' in the Hue.ini dump but still dont have any spark notebook available. This may be due to the dependency on Spark Parcels being installed.   If I have to re-install the cluster onto Linux RedHat to activate the Spark Parcels that could be a possibility, but I'd prefer to get everything working on ubuntu 14.04 first if possible.   Any guidance on which route to take would be appreciated.   Regards   natdacruz        ...
