You use basic authentication. You should just be able to send your query to druid with an URL like this:

HDFS as Deep-Storage: Druid is not storing the historical data on hdfs

Asked 2019-Dec-12 at 11:09

I have set up a micro-server of Druid on on-prem machine. I want to use HDFS as deep-storage of druid. I have used the following Druid Docs, [druid-hdfs-storage] fully qualified deep storage path throws exceptions and imply-druid docs as references.

I have made following changes in /apache-druid-0.16.0-incubating/conf/druid/single-server/micro-quickstart/_common/common.runtime.properties

I resolved the issue by changing the hdp.version in the mapred-site.xml manually. I was getting following exception in middleManager.log

java.lang.IllegalArgumentException: Unable to parse '/hdp/apps/${hdp.version}/mapreduce/mapreduce.tar.gz#mr-framework' as a URI, check the setting for mapreduce.application.framework.path

But Still the segment metadata is showing Request failed with status code 404.

How do I enable logging/tracing in Apache Calcite using Sqlline?

Asked 2019-Jun-18 at 08:29

Following https://calcite.apache.org/docs/tutorial.html, I ran Apache Calcite using SqlLine. I tried activating tracing as instructed in https://calcite.apache.org/docs/howto.html#tracing. However, I don't get any logging. Here is the content of my session (hopefully containing all relevant information):

I have the impression that problem lies to the underlying implementation of the logger.

I am not an expert on logging configurations but I think specifying the properties file through -Djava.util.logging.config.file does not have any effect since the logger that is used (according to the classpath you provided) is the Log4J implementation (slf4j-log4j12-1.7.25.jar) and not the one of the jdk (https://mvnrepository.com/artifact/org.slf4j/slf4j-jdk14/1.7.26).

I think that the right property to use for the log4j implementation is the folowing: -Dlog4j.configuration=file:C:\Users\user0\workspaces\apache-projects\apache-calcite\core\src\test\resources\log4j.properties

"Failed to submit supervisor: Request failed with status code 502" on submitting ingestion spec to router

Asked 2019-May-22 at 11:36

I am getting the error "Failed to submit supervisor: Request failed with status code 502" when I am trying to submit an ingestion spec to the druid UI (through the router). The ingestion spec works in a standalone druid server.

I have set up the cluster using 4 machines-1 for the coordinator and overlord (master), 1 for historical and middle manager (data), 1 for broker (query), and 1 for router, with a separate instance for zookeeper. There is no error in the logs.

The ingestion spec is as follows:

ANSWER

Answered 2019-May-22 at 11:36

It happened because the druid-kafka-indexing-service extension was missing from the extension list of common.runtime.properties.
