How to obtain Phoenix table data via HBase REST service

Question

I created a HBase table using the Phoenix JDBC Driver in the following code snippet:

    Class.forName(\"org.apache.phoenix.jdbc.PhoenixDriver\");
    Connection         


        

Answer 1

You probably have an issue with how Phoenix encodes data it stores in an HBase table, vs how the native REST API will try and find a key.

Looking at the Phoenix documentation on data types for BIGINT it says:

The binary representation is an 8 byte long with the sign bit flipped (so that negative values sorts before positive values).

So you should probably take a look at what has actually been inserted into your table. The HBase REST API is probably looking for a key using a different encoding and thus can't find it.

Answer 2

You really should get your data from phoenix table using phoenix not HBase. Phoenix use is custom encoding for it's Integer and BigInt also salting (if you use one).

Phoenix also mostly use byte for storing data and StringBinary for encoding it. So, lot of chance that your key is not 5 but \x80\x00\x00\x05(Integer)
