Question

我们正在尝试一系列操作，例如SELECT - ＆gt;将行密钥存储到集合中 - ＆gt;然后将集合拆分为每个工作线程 - ＆gt;每个线程再次使用phoenix jdbc创建连接 - ＆gt;然后根据结果UPSERT执行SELECT到另一个凤凰表。

我正在使用具有固定线程池4的ExecutorService，我看到如下例外情况。

但如果我使用2或更小的池大小，它可以正常工作。我想知道客户端是否有可以更改的属性？

Answer 1

我的情况我通过在pom.xml中使用以下依赖项来解决这个问题

<dependency>
            <groupId>org.apache.hbase</groupId>
            <artifactId>hbase-protocol</artifactId>
            <version>1.1.11</version>
</dependency>

只是为了更新你我有Hbase版本：1.1和凤凰是4.7

Answer 2

hbase-site.xml中的

phoenix.spool.directory修复了这个问题。感谢

Apache phoenix并发查询失败，异常
