kandi X-RAY | datasketches Summary

datasketches is a C++ library. datasketches has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is the core C++ component of the DataSketches library. It contains all of the key sketching algorithms that are in the Java component and can be accessed directly from user applications. This component is also a dependency of other components of the library that create adaptors for target systems, such as PostgreSQL. Note that we have a parallel core component for Java implementations of the same sketch algorithms, incubator-datasketches-java. Please visit the main DataSketches website for more information. If you are interested in making contributions to this site please see our Community page for how to contact us. This code requires C++11. It was tested with GCC 4.8.5 (standard in RedHat at the time of this writing), GCC 8.2.0 and Apple LLVM version 10.0.1 (clang-1001.0.46.4). This includes Python bindings. For the Python interface, see the README notes in the python subdirectory. This library is header-only. The build process provided is only for building unit tests and the python library. Building the unit tests requires cmake 3.12.0 or higher. Installing the latest cmake on OSX: brew install cmake.

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

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.

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.
