java - Hbase byteArray to Long -

i have row key being created

put put  = new put(bytes.tobytes(tweets.getcontact_unique_id()+"^"+bytes.tobytes(epoch))); 

where epoch long timestamp.

now when scan row

3857^[b@7c8f4424

now wish convert part of rowkey ie long

[b@7c8f4424

how achieve this.

edit -> if use put

put put = new put(bytes.tobytes(tweets.getcontact_unique_id() + "^" + epoch);

not rows gets inserted , when use

put put = new put(bytes.tobytes(tweets.getcontact_unique_id()+"^"+bytes.tobytes(epoch)));

all rows gets inserted , please note time values different.

also note have used "^" seperate out 1st , 2nd part of rowkey.

thanks

you save long value in a wrong way!

because when use + array bytes of long value converts string, converted value shows the current address in memory of bytes array, not value!

---

the correct way of saving:

put put  = new put(bytes.add(bytes.tobytes(tweets.getcontact_unique_id() + "^"), bytes.tobytes(epoch))); //i kept "^", don't know why need 

and retrieving:

// row byte array of key // bytes.tail(..) gets tail of key's bytes bytes of long // bytes.tolong(..) converts long bytes long // 8 corresponds long size in bytes bytes.tolong(bytes.tail(row, 8))
