---------------------------------------------

             Summary: StateStore writer should not commit tmp fail if there was 
an error in writing the file.
                 Key: HDFS-16847
                 URL: https://issues.apache.org/jira/browse/HDFS-16847
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Simbarashe Dzinamarira


The file based implementation of the RBF state store has a commit step that 
moves a temporary file to a permanent location.

There is a check to see if the write of the temp file was successfully, 
however, the code to commit doesn't check the success flag.

This is the relevant code: 
[https://github.com/apache/hadoop/blob/7d39abd799a5f801a9fd07868a193205ab500bfa/hadoop-hdfs-project/hadoop-hdfs-rbf/src/main/java/org/apache/hadoop/hdfs/server/federation/store/driver/impl/StateStoreFileBaseImpl.java#L369]
