Rongnengwei opened a new pull request #995: KYLIN-4206 Add kylin supports aws glue catalog metastroeclient URL: https://github.com/apache/kylin/pull/995 This modification mainly solves the problem of aw glue catalog supported by kylin, and the associated jira is [https://issues.apache.org/jira/browse/KYLIN-4206](https://issues.apache.org/jira/browse/KYLIN-4206)。 1.First you need to modify the aws-glue-data-catalog-client source code. aws-glue-data-catalog-client-for-apache-hive-metastore github address is https://github.com/awslabs/aws-glue-data-catalog-client-for-apache-hive-metastore，aws-glue-client development environment see README.MD. I downloaded hive 2.3.7 locally, so after following the steps in the README.MD file, the version of hive is 2.3.7-SNAPSHOT. 1）Modify the pom.xml file in the home directory. <hive2.version>2.3.7-SNAPSHOT</hive2.version> <spark-hive.version>1.2.1.spark2</spark-hive.version> 2)Modify the class of aws-glue-datacatalog-hive2-client/com.amazonaws.glue.catalog.metastore.AWSCatalogMetastoreClient Implementation method ``` @Override public PartitionValuesResponse listPartitionValues (PartitionValuesRequest partitionValuesRequest) throws MetaException, TException, NoSuchObjectException { return null; } ``` 3)Modify the class of aws-glue-datacatalog-spark-client/com.amazonaws.glue.catalog.metastore.AWSCatalogMetastoreClient. The problems are as follows： This method is not available in the parent class，so delete the method，Then copy the method of aws-glue-datacatalog-hive2-client / com.amazonaws.glue.catalog.metastore.AWSCatalogMetastoreClient.Add dependency in aws-glue-datacatalog-spark-client / pom.xml file ``` <dependency> <groupId>org.apache.hive</groupId> <artifactId>hive-exec</artifactId> <version>${hive2.version}</version> <scope>provided</scope> ``` </dependency> 4）Package，need to package three projects,as follows. aws-glue-datacatalog-client-common aws-glue-datacatalog-hive2-client aws-glue-datacatalog-spark-client 5).Copy the three package aws-glue-datacatalog-client-common-1.10.0-SNAPSHOT.jar aws-glue-datacatalog-hive2-client-1.10.0-SNAPSHOT.jar aws-glue-datacatalog-spark-client-1.10.0-SNAPSHOT.jar to /kylin/lib 2.Modify the source code of kylin,See submission of PR. 1)Add the gluecatalog in the config of kylin.properties. ``` ##The default access HiveMetastoreClient is hcatalog. If AWS user and glue catalog is used, it can be configured as gluecatalog ##kylin.source.hive.metadata-type=hcatalog ``` The default is hcatalog. If you want to use glue, please configure kylin.source.hive.metadata-type = gluecatalog. if config gluecatalog,so need to configure in hive-site.xml，as follows: ``` <property> <name>hive.metastore.client.factory.class</name> <value>com.amazonaws.glue.catalog.metastore.AWSGlueDataCatalogHiveClientFactory</value> </property> ``` 3.install on EMR
