Question

当我尝试使用hadoop 2.2.0在oozie 4.0.1中运行map-reduce作业时。我收到以下错误

hadoopuser@hadoopmaster:/usr/lib/oozie-4.0.1/distro/target/oozie-4.0.1-distro/oozie-4.0.1$ oozie job -oozie http://hadoopmaster:11000/oozie -log 0000001-141029094805376-oozie-hado-W

当我访问该作业ID的oozie.log时，我发现身份验证令牌已过期警告，然后＆＃39;凭据对于操作＆＃39;错误。

请帮帮我。很长一段时间我都陷入了这个错误。任何帮助将不胜感激。

对于操作，凭据为空 - 在oozie中运行mapreduce作业时发现错误
