和Java 8

Question

我从本地机器连接到Bigtable，遵循这个例子。当我使用JDK 7运行我的项目时，一切都很完美，但是当使用JDK 8运行它时，我有以下内容：

Exception in thread "main" java.io.IOException: Failed to create table 'testTable'

看来java 8中的sun库有变化。有办法在java 8下运行这段代码吗？

Answer 1

HBase还没有通过运行Java 8的认证。目前，请继续使用Java 7。下面是两个HBase / Hadoop跟踪bug：

https://issues.apache.org/jira/browse/HADOOP-11090 https://issues.apache.org/jira/browse/HBASE-7608

Answer 2

在我自己寻找答案的时候偶然发现了这一点。

我能够让它在我的引导路径中使用ALPN的正确版本。

对于Java 8，我使用了ALPN版本的8.1.4.v20150727。
