Hi,
When I backported HBASE-5358 for 0.92, I was bringing the following into
HbaseObjectWritable.java:
+ //java.lang.reflect.Array is a placeholder for arrays not defined
above
+ GENERIC_ARRAY_CODE = code++;
+ addToMap(Array.class, GENERIC_ARRAY_CODE);
We had to handle the two classes which aren't in 0.92:
addToMap(Append.class, code++);
addToMap(RowMutation.class, code++);
I planned to use dummy classes in their place so that GENERIC_ARRAY_CODE
stays the same for 0.92 and 0.94
Enis suggested creating private final dummy class for the above purpose.
This is what went into 0.92:
// the following class is used to fill potential holes in
// CODE_TO_CLASS and CLASS_TO_CODE so that concrete classes have
// the same ordinals across major releases
private final static class DummyType {
}
In the future, please make use of the above class when backporting.
Cheers
