Question

我正在尝试使用HCatalog读取和写入数据，我读到我得到的以下错误是因为版本不匹配，尝试更改hive和hadoop的版本，但还没有运气。任何帮助高度赞赏。

的信息：

INFO: output schema explicitly set for writing:groupname:org.apache.hive.hcatalog.data.schema.HCatFieldSchema@17c565b8[fieldName=groupname,comment=<null>,type=string,category=PRIMITIVE],id:org.apache.hive.hcatalog.data.schema.HCatFieldSchema@20991f39[fieldName=id,comment=<null>,type=int,category=PRIMITIVE]

以下是类路径变量：
HADOOP_HOME = /usr/local/Cellar/hadoop-2.6.0
HIVE_HOME = /usr/local/Cellar/apache-hive-1.1.0

在POM中，这些是依赖关系：

Answer 1

我自己解决了。下载了hive 1.1.0的源代码，使用此命令在本地构建

mvn clean install -Phadoop-2,dist -DskipTests

并使用形成的二进制文件，它开始工作。
