猪将hdfs数据导入hbase时出错

Question

我的集群的版本是{hadoop2.7.1，hbase 1.1.2，pon0.15}我尝试通过pig将hdfs数据导入到hbase中，但是我发现了问题，错误日志显示如下：

Answer 1

Pig只包括HBase版本< 1.0的HBase连接器(查看Pig的lib以获得特定的Pig版本)，以保持hadoop1兼容性。

您必须降级到HBase的那个版本，或者根据HBase 1.1.2从源代码中重新编译Pig。

编辑:在这里更详细地讨论：https://issues.apache.org/jira/browse/PIG-4728

Answer 2

您可以选择其他版本，而这种集成正在为我工作。

Hadoop 2.5.2，hbase 0.98猪0.15

我希望你的问题能得到解决
