Description

https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/container-executor.c

 

Has several different ways for reporting errors:

 

1. Couldn't
2. Can't
3. Could not
4. Failed to
5. Unable to
6. Other

 

I think "Failed to" is the best verbage.  Contractions are hard for non-native English speaking folks.  "Failed" is to the point. and more likely to grep logs for 'fail' than I am 'unable' or 'could not'.
