Docker Cloudera image Hue login issues

pollard — Fri, 16 Sep 2022 13:42:55 GMT

Hi,

I have just successfully run a Docker container image of Cloudera. I can connect to the instance using Safari on the Mac. However, I get an error message that says it can't connect:

"Could not connect to quickstart.cloudera:21050 (code THRIFTTRANSPORT): TTransportException('Could not connect to quickstart.cloudera:21050',)"

Also, when I do a check configuration it comes up with a bunch of errors:

hadoop.hdfs_clusters.default.webhdfs_url	Current value: http://localhost:50070/webhdfs/v1 Failed to access filesystem root
OOZIE_EMAIL_SERVER	Email notifications is disabled for Workflows and Jobs as SMTP server is localhost.
Hive	Failed to access Hive warehouse: /user/hive/warehouse
HBase Browser	Failed to authenticate to HBase Thrift Server, check authentication configurations.
Impala	No available Impalad to send queries to.
Hadoop Security: Sentry Service	Failed to connect to Sentry API (version 1).
Hadoop Security: Sentry Service	Failed to connect to Sentry API (version 2).

Anyone have a direction they can point me on how to resolve all of these issues. I thought the Docker image would work out of the box.

Thanks!

@pollard,

Are any of your services running? Maybe provide a screen shot of Cloudera Manager's home page and also the hosts page.

"Could not connect to quickstart.cloudera:21050" means that Hue cannot connect to the impala daemon so make sure that it is running and listening on port 21050

According to the output logs:

Using CATALINA_BASE: /var/lib/solr/tomcat-deployment

Using CATALINA_HOME: /usr/lib/solr/../bigtop-tomcat

Using CATALINA_TMPDIR: /var/lib/solr/

Using JRE_HOME: /usr/java/jdk1.7.0_67-cloudera

Using CATALINA_PID: /var/run/solr/solr.pid

Started Impala Catalog Server (catalogd) : [ OK ]

Started Impala Server (impalad): [ OK ]

Yes, impalad is running. But, according to "ps aux" it is not:

ps aux | grep -i impala

impala 2693 0.1 0.0 357552 612 ? Sl Sep14 6:24 /usr/lib/impala/sbin/statestored -log_dir=/var/log/impala -state_store_port=24000

impala 3077 0.3 3.0 1034932 62260 ? Sl Sep14 13:46 /usr/lib/impala/sbin/catalogd -log_dir=/var/log/impala

There's no "impalad" process running. I assumed the log was correct and did not check.

The "catalogd.quickstart.cloudera.impala.log.ERROR.20180914-185251.3077" log contains:
