Hadoop 配置单元错误：metastore.RetryingRawStore:JDO数据存储错误。在1000毫秒后重试metastore命令（尝试1次，共1次）

我正在运行Sybase作为我的Hive的metastore。 我已经对数据库给予了适当的许可。 但在执行基本命令时遇到问题。（显示表格）

以下是调试模式下作业的输出：

您可能有以下一（多）个问题：

1.）请检查是否在SyBase的配置单元库中放置了正确的连接器jar

2.）您的SyBase服务器正在运行吗

3.）您是否在hive-site.xml中输入了正确的用户名/密码/连接URL

希望这有帮助

我也犯了类似的错误。。这可能是由于Hive Metastore（HMS）无法启动。您可能需要重新启动为我工作的HMS服务。希望这有帮助

哪个是您的

操作系统

？如果是

Linux

，则检查是否启用了

SeLinux

。您可以通过在终端中发出

sestatus

来实现这一点。元存储错误与操作系统有何关系？对于您的信息，SeLinux当前已禁用。您好，启用SeLinux时，metastore曾出现问题。但是，由于在您的情况下它被禁用，我认为不是SELinux导致了问题。但是您提到您正在运行一个

SHOW TABLES

，但是错误消息的最后一行说

CREATE TABLE

。默认情况下，传输中的

ddl

设置为

False

。我没有将

Sybase

与

Hive

一起使用，但是可以通过将

tran

中的ddl设置为

True

（这不是建议的选项）或从事务中移出ddl来覆盖此错误。请尝试编辑此帖子的外观，并添加有关所用过程的更多详细信息。
