You'll need to flip the sign bit for ints and longs like Phoenix does.
Feel free to borrow our serializers (in PDataType) or just use Phoenix.

this is the correct mail..
We have implemented QualifierFilter as well as ValueFilter (using
BinaryComparator) of Hbase successfully and they are working fine for most
of our cases. However they are failing in cases like number > -10 or number
< -10
Please note that number = -10 is working perfectly fine. Also, number > 10
and number < 10 are also working fine.
If you want to see the code, please check following links:
1. QualifierFilter - Relevant lines are 126-142
https://github.com/deanhiller/playorm/blob/master/src/main/java/com/alvazan/orm/layer9z/spi/db/hadoop/CursorColumnSliceHbase.java
2. Value Filter - Relevant lines are 107-128
https://github.com/deanhiller/playorm/blob/master/src/main/java/com/alvazan/orm/layer9z/spi/db/hadoop/CursorOfHbaseIndexes.java
As per this blog(http://flurrytechblog.wordpress.com/2012/06/12/137492485/),
this can be an issue with serialization if we want to store negative values
for rowkeys and we should write our own serializers for comparison.
So we wanted to know:
1. Is it really necessary to write our own serializer in this case?
2. If yes, how? Any example would be great help.
