Hi Gabriel, But why then I receive in HBase shell two different string representation of the byte array? For byte arrays stored from phoenix - \x00\x00\x00\x00I\x96\x02\xD2 and [B@13217cf6 for stored from HBase. The same time phoenix have wrong understanding of "[B@13217cf6" and receives -323837278362736236786-like value instead 1234567890 I have to understand the way to store values via hbase API but read from phoenix then correctly.

There's more information on the various types and their underlying encoding available here: http://phoenix.apache.org/language/datatypes.html I'm guessing you got the string representation ("\x00\x00\x00\x00I\x96\x02\xD2") from the HBase shell -- this is a string representation of the byte array (containing 8 bytes) containing the serialized value of 1234567890. The strings you posted like "[B@13217cf6" are the default string representation of byte arrays in java. To convert these to a human-readable value (like what the HBase shell does), you could do the following: Bytes.toStringBinary(Bytes.toBytes(1234567890L)); - Gabriel On Thu, Jan 8, 2015 at 9:44 AM, Lavrenty Eskin <lavrenty.es...@netcracker.com> wrote: > Helo all, > I'm surprised that phoenix store numbers not in HBase 'Byte' format.
