I have installed a single node instance on a m3.2xlarge AWS EC2 Instance with EBS so I can stop and start it (using the very nice http://gethue.com/hadoop-tutorial-how-to-create-a-real-hadoop-cluster-in-10-minutes/).  I am trying to use it to test a solr implementation that I have.  I have used the CDH 5.2 (Cloudera Express)  installer my cluster is all green.  I can launch Solr and it seems good though no clusters are installed.    I receive the following error message when I try to install the Hue - Quick Start application samples for Solr Search on the Hue Quick Start Tab Step 2 Examples.  "Could not create instance directory. Check if [indexer] solr_zk_ensemble is correct in Hue config and look at the Solr error logs for more info".   I have tried to changing the Hue configuration with the Hue Server Configuration Advanced Configuration Snippet for hue_safety_valve_server.ini to: [search] ## URL of the Solr Server solr_url=http://SOLR_HOST:8983/solr   and I get the following message:  [Errno 13] Permission denied: '/opt/cloudera/parcels/CDH-5.2.0-1.cdh5.2.0.p0.36/lib/hue/desktop/libs/indexer/src/indexer/../data/collections'   I also tried using ## URL of the Solr Server solr_url=http://<AWS Public DNS> SOLR_HOST:8983/solr in the Hue configuration and I get the following: "Could not create instance directory. Check if [indexer] solr_zk_ensemble is correct in Hue config and look at the Solr error logs for more info" the same as not configuring this parameter.   I was able to install this on Ubantu 14 Trusty and somehow was able to get it to install but I could not stop and start the AWS instance... it trashed the HDFS service so that it was unusable.   Any suggestions would be appreciated.     ...
