Description
In some environments it may be the case that the local unix usernames are different than the ones in Kerberos account. This feature lets you override the username and map it to the one locally available.
Added settings:
storm.principal.mapper.regex = what to replace in the existing principal
storm.principal.mapper.replacement = what to replace in the existing principal with
e.g.
Kerberos principal is 0001@storm.apache.org
storm.principal.mapper.regex=^
storm.principal.mapper.replacement=A
Would result in local principal=A0001
