Raju commented on HDFS-3735:
----------------------------
Hey Brahma,
{code}
case FIELD_FAILED_VOL:
ret = d1.getVolumeFailures() - d2.getVolumeFailures();
break;
{code}
Since we are using this code in comparator its good to return -1,0 or 1 as its
return value. Even without that with current fix it will work. But in general
the mentioned values are returned.
