Description

The caller context is a value supplied by applications and included in HDFS audit log entries. The scope of this issue is to define a constrained grammar for those values and enforce it with validation logic in the code. Since the values reach the HDFS audit log, there is an expectation that the values need to be easily machine parseable.
