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

             Summary: The Quata class's andByStorageType method res has an 
incorrect initial value
                 Key: HDFS-17214
                 URL: https://issues.apache.org/jira/browse/HDFS-17214
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: rbf
    Affects Versions: 3.3.4
            Reporter: xiaojunxiang


The Quata class's andByStorageType method is intended to apply bitwise and to 
each bit of StorageType.values( ) (the converted value), returning true only if 
all the values are true.
So the initial value of res should be true and then loop through the array to 
perform the bitwise and operation. 
However, since res starts with fasle, the bitwise and always evaluates to 
false, so we should fix res to start with true.
