hadoop - HBase批量加载异常

Question

我能够使用 Java 程序生成 HFile，但每当我尝试将它们导入我的 HBase 表时，我都会收到附加错误。当我没有使用我的 Java 程序，而是使用 completebulkload 时，我遇到了同样的错误。

如果有人能在这里帮助我，那将是一个很大的帮助。几天来我一直坚持这个问题，开始变得非常沮丧。

亲切的问候，彼得扬

Answer 1

终于找到了解决办法。

我确保 $HBASE_HOME/conf 下的文件夹位于我的 Java 应用程序的类路径中，并在我的代码中添加了 SchemaMetrics.configureGlobally(conf) 设置在指标名称中使用表名称的标志。

我希望这对以后的人有帮助。

编辑:我发现后一件事是我必须使用 HBase 0.94.3 做的事情。
