> {{ClientHSSecurityInfo}} is located in 
> {noformat}
> ./hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/src/main/resources/META-INF/services/org.apache.hadoop.security.SecurityInfo
> {noformat} 
> But the actual class exists in
> {noformat}
> hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-common
> {noformat}
> Because of this issue, there is an ordering dependency between the 
> client-jobclient and client-common that can cause failures if the ordering is 
> not correct. Namely, if client-common is in the classpath _after_ 
> client-jobclient, the JVM won't find {{ClientHSSecurityInfo}}
