Question

我正在尝试在Windows 8机器上启动Apache nifi 1.2.0版。它过去常常正常启动。重新启动系统后，nifi根本没有启动。我有检查状态它一直在＆＃34; Apacha Nifi没有运行＆＃34;。

以下是来自nifi.bootstrap.log文件的日志： -

Answer 1

在谷歌搜索此错误后“由以下原因引起：java.io.IOException：预计读取'1'的Sentinel字节，但得到的值为'0'”我发现此错误表示部分写入回购

以下是您可以检查/尝试将数据流重新联机的一些事项;

检查您的dsks是否未满
您是否使用同一位用户启动了nifi？你是否以管理员权限运行它？
您可以备份/移动存储库并尝试使用空存储库启动Nifi，但仍然会有数据流，但是当您关闭时正在处理的任何文件都将消失。

你可以试试吗？

Apache nifi无法启动
