Question

我们昨天看到公共Cosmos实例已进入安全模式，我们无法更新，写入或删除任何文件。今天我们看到我们无法读取 - 打开任何文件。

当我们尝试打开hadoop文件时，我们收到此错误：

Java HotSpot(TM) 64-Bit Server VM warning: Insufficient space for shared memory file:
   /tmp/hsperfdata_jonmikel.alonso/22367
Try using the -Djava.io.tmpdir= option to select an alternate temp location.

Exception in thread "main" java.lang.NoClassDefFoundError: ___/tmp/hsperfdata_jonmikel/alonso/22379

这似乎已经发生过：

Fi-Ware Cosmos: Name node is in safe mode

SafeModeException at cosmos.lab.fi-ware.org

宇宙再次进入安全模式。没有读，没有写，没有更新
