HBase模型包含以下类型(type):
- Entity types:
- hbase_namespace
- super-types: !Asset
- attributes: qualifiedName, name, description, owner, clusterName, parameters, createTime, modifiedTime
- hbase_table
- super-types: DataSet
- attributes: qualifiedName, name, description, owner, namespace, column_families, uri, parameters, createtime, modifiedtime, maxfilesize, isReadOnly, isCompactionEnabled, isNormalizationEnabled, ReplicaPerRegion, Durability
- hbase_column_family
- super-types: DataSet
- attributes: qualifiedName, name, description, owner, columns, createTime, bloomFilterType, compressionType, compactionCompressionType, encryptionType, inMemoryCompactionPolicy, keepDeletedCells, maxversions, minVersions, datablockEncoding, storagePolicy, ttl, blockCachedEnabled, cacheBloomsOnWrite, cacheDataOnWrite, evictBlocksOnClose, prefetchBlocksOnOpen, newVersionsBehavior, isMobEnabled, mobCompactPartitionPolicy
- hbase_namespace
使用唯一属性qualifiedName在Atlas中创建和删除HBase实体,其值应格式如下所述。请注意,namespaceName,tableName和columnFamilyName应为小写。
hbase_namespace.qualifiedName: <namespaceName>@<clusterName>
hbase_table.qualifiedName: <namespaceName>:<tableName>@<clusterName>
hbase_column_family.qualifiedName: <namespaceName>:<tableName>.<columnFamilyName>@<clusterName>
Atlas HBase hook与HBase master注册为协处理器。在检测到对HBase名称空间/表/列族的更改时,Atlas Hook过Kafka通知更新Atlas中的元数据。按照以下说明在HBase中设置Atlas Hook:
通过添加以下内容在hbase-site.xml
中注册Atlas hook:
<property>
<name>hbase.coprocessor.master.classes</name>
<value>org.apache.atlas.hbase.hook.HBaseAtlasCoprocessor</value>
</property>
- 解压
apache-atlas-${project.version}-hbase-hook.tar.gz
cd apache-atlas-hbase-hook-${project.version}
- 将文件夹
apache-atlas-hbase-hook-${project.version}/hook/hbase
的全部内容复制到<atlas package>/hook/hbase
- 在HBase类路径中链接Atlas hook jar
ln -s <atlas package>/hook/hbase/* <hbase-home>/lib/
- 将
<atlas-conf>/atlas-application.properties
复制到HBaseconf
目录。
atlas-application.properties
中的以下属性控制线程池和通知详细信息:
atlas.hook.hbase.synchronous=false # whether to run the hook synchronously. false recommended to avoid delays in HBase operations. Default: false
atlas.hook.hbase.numRetries=3 # number of retries for notification failure. Default: 3
atlas.hook.hbase.queueSize=10000 # queue size for the threadpool. Default: 10000
atlas.cluster.name=primary # clusterName to use in qualifiedName of entities. Default: primary
atlas.kafka.zookeeper.connect= # Zookeeper connect URL for Kafka. Example: localhost:2181
atlas.kafka.zookeeper.connection.timeout.ms=30000 # Zookeeper connection timeout. Default: 30000
atlas.kafka.zookeeper.session.timeout.ms=60000 # Zookeeper session timeout. Default: 60000
atlas.kafka.zookeeper.sync.time.ms=20 # Zookeeper sync time. Default: 20
可以通过在配置名称前加上“atlas.kafka”前缀来指定Kafka通知生成器的其他配置。有关Kafka制作人支持的配置列表,请参阅Kafka Producer Configs
Atlas HBase hook仅捕获名称空间、表和列族的创建/更新/删除操作。将捕获对列的更改。
Apache Atlas提供了一个命令行脚本import-hbase.sh
,用于将Apache HBase名称空间和表的元数据导入Apache Atlas。此脚本可用于使用Apache HBase集群中存在的名称空间/表初始化Apache Atlas。此脚本支持导入特定表的元数据,特定命名空间中的表或所有表。
Usage 1: <atlas package>/hook-bin/import-hbase.sh
Usage 2: <atlas package>/hook-bin/import-hbase.sh [-n <namespace regex> OR --namespace <namespace regex>] [-t <table regex> OR --table <table regex>]
Usage 3: <atlas package>/hook-bin/import-hbase.sh [-f <filename>]
File Format:
namespace1:tbl1
namespace1:tbl2
namespace2:tbl1
