How to get string from hbase composite key?

[kitex101]

I have key in following format:

byte[] rowKey =
=Bytes.add(Bytes.toBytes("3"),Bytes.toBytes(98),Bytes.toBytes(1211));

It is stored as byte array.

How to decode it when using java?

Bytes.toString(CellUtil.cloneRow(cell)) 

results in a�~��

So, it would be like manually getting 4 byte. Actually they are long.

Query data like opentsdb

[kitex101]

I have key design like:byte[] rowKey =
=Bytes.add(Bytes.toBytes("3"),Bytes.toBytes(customer_id),Bytes.toBytes(timestamp));
customer_id and timestamp are long type. As opentsdb uses:[…]I would like to
filter my key by customer_id and timestamp. How do I do that?I have tried
using prefixfilter. e.g.byte[] prefix = Bytes.add(Bytes.toBytes("3"),
Bytes.toBytes(customer_id),Bytes.toBytes(cal.getTime().getTime()));   
PrefixFilter prefixFilter = new PrefixFilter(prefix); Scan scan = new Scan( 
  
prefix);
