Gera Shegalov updated YARN-3768:
--------------------------------
Attachment: YARN-3768.003.patch
Thanks for reviewing the patch, [~zxu]!
bq. If the input is "a=b=c", it saves Env variable "a" with value "b". Is it
correct?
Correct, and I agree it does not look the behavior we want. I think the right
behavior is to accept any value between the first {{=}} and the next {{,}}. The
value should be {{b=c}} in your example.
bq. I also noticed the patch will discard Env Variable with empty string value.
I am ok with it.
I think it might be desirable sometimes to clear a variable that is is set
globally. Let us allow it.

> Looking at line 80 of org.apache.hadoop.yarn.util.Apps an index out of range
> exception occurs if an environment variable is encountered without a value.
> I believe this occurs because java will not return empty strings from the
> split method. Similar to this
