I downloaded the Cloudera QuickStart VM v.5.5. a couple of days ago. It seems to work fine except that when I navigated to the Hive Editor, I see the message: Could not connect to quickstart.cloudera:10000 (I am logged in as the user "cloudera"; this VM is running on a Win 7 host) So I checked the current configuration of the VM (by clicking on the Hue icon in the upper left corner) and I see these messages (which may be related) under the "Step 1: Check configuration" tab: Configuration files located in /etc/hue/conf.empty Potential misconfiguration detected. Fix and restart Hue. hadoop.hdfs_clusters.default.webhdfs_url Current value: http://localhost:50070/webhdfs/v1 Failed to create temporary file "/tmp/hue_config_validation.9867056700988081108" Hive Editor The application won't work without a running HiveServer2. If I click to install the "Hive Editor" under the "Check 2: Examples tab", I get this error: ...Could not connect to quickstart.cloudera:10000 (code THRIFTTRANSPORT): TTransportException... The messages seems to imply that HiveServer2 is not running, but executing below two lines in the command window... sudo service hive-server2 stop sudo service hive-server2 start ...gives me the below messages but does not resolve the problem: Stopped Hive Server2: [ OK ] Started Hive Server2 (hive-server2): [ OK ] So I took a look at the "hue.ini" file located in /etc/hue/conf.empty; the configuration settings for hive connectivity (under the [beeswax] section) are: hive_server_host=quickstart.cloudera hive_server_port=10000 Above seemed correct (considering that the Firefox browser on this VM is able to connect to Hue through the socket "quickstart.cloudera:8888"). However trying to connect by executing these lines in a command window... /usr/lib/hive/bin/beeline !connect jdbc:hive2://localhost:10000 hive cloudera org.apache.hive.jdbc.HiveDriver (The "hive"/"cloudera" credentials are taken from hive-site.xml) ...gives me the error: java.net.ConnectException: Connection refused (state=08S01,code=0) It looks like the reason for the error is that nothing is listening on port 10000, as at least the command... sudo netstat -tulp | grep :100 ...does not show anything listening on port 10000. Any thoughts on how to solve this issue?
