JobClient does not initialize conf member in all constructors
-------------------------------------------------------------
Key: MAPREDUCE-3609
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3609
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.20.205.0
Reporter: Gilad Wolff
Priority: Minor
The c'tor that takes a socket address does not initialize the configuration
member:
public JobClient(InetSocketAddress jobTrackAddr,
Configuration conf) throws IOException {
this.ugi = UserGroupInformation.getCurrentUser();
jobSubmitClient = createRPCProxy(jobTrackAddr, conf);
}
It should call setconf(conf). This leads to an NPE if a caller instantiates a
job client using the c'tor and tries to retrieve a job since the NetworkedJob
c'tor tries to access the configuration.
The workaround is simple but "ugly" - the caller can call setconf explicitly.
I only checked on 0.20.205.0 but the problem may also exist upstream.
