------------------------------------------------
Summary: Generating secrets for authenticating shuffle transfer is
not Fedramp compliant
Key: MAPREDUCE-7189
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7189
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: job submission
Reporter: Gopi Krishnan Nambiar
Currently, the mode of generating secrets for authenticating shuffle transfers
is not Fedramp compliant.
See
[https://github.com/apache/hadoop/blob/a49cb4465e6849a4346dcfa6f4a235d6fde917d3/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/JobSubmitter.java#L177]
to see the relevant sections.
Specifically the HMAC/SHA1 algorithm does not have the requisite key length of
at least 112 bits for Fedramp High compliance and the HMAC/SHA1 is not
compliant and needs to be changed to SHA-256/HMAC instead,
