We saw yesterday that public Cosmos instance had entered safe mode and we couldn't update, write or delete any file. And today we see we can't read - open any file.

When we tried to open a hadoop file we get this error:

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

Could not find the main class: ___/tmp/hsperfdata_jonmikel.alonso/22379.  Program will exit.

It seems this already happened before:

Fi-Ware Cosmos: Name node is in safe mode

SafeModeException at cosmos.lab.fi-ware.org

  • This has been fixed. – frb Dec 10 '15 at 07:22
  • I'm voting to close this question as off-topic because it is about a temporal problem in a SaaS infrastrecture (currently fixes, as I read in the comments) not useful for the community. – fgalan Dec 21 '15 at 13:17
