我一直在尝试使用bigdatabatch中的hbaseinput组件从hbase表中获取数据。
我没有在tmap中执行任何转换,只是尝试从hbase表中读取数据。我检查了所有连接,它们连接良好。最后,我构建了一个作业,复制它并在集群中运行。这份工作给了我以下例外情况,
[WARN ]: org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper - Possibly transient ZooKeeper, quorum=zk:5181, exception=org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid

这是表名,
它编写了行键,我在组件中硬编码了行键。其余的田地都是空的。是的,我在表中有数据,它有数百万行。我认为talend无法从我的表中获取数据,它没有与之通信,正如异常所说的“由:java.lang.illegalargumentexception:java.net.urisyntaxexception:relative path in absolute引起”uri:namespace1:表“名称”
**这是指定表名的正确方法吗?
为什么我不从表中选取数据**

您使用的是mapr发行版,它与其他hadoop发行版稍有不同。
最后,您可以进入
tHbaseInput
组件并设置以下属性:或检查
Set table Namspace mappings
框并将Map放到表中。看这里。
