    Description

      FIPS-compliant HMAC-SHA1 algorithms require secret keys to be at least 112 bits long. https://github.com/apache/hadoop/blob/231a4468cdb83f9c2ff8897e70fe7c3d23b58cf4/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/JobSubmitter.java#L180 could be made configurable in order to remain FIPS-compliant.
