Re: Custom HBase Filter : Error in readFields

Also the readFields is your implementation of how to read the byte array
transferred from the client. So I think there has to be some issue in how
you write the byte array to the network and what you are reading out of
that i.e. the size of arrays might not be identical.

But as Ted mentioned, looking at the code will help troubleshoot it better.
