You are asking Stargate for XML representation. HBase stores data of arbitrary byte[]. Also, characters like '<' and '>' will confuse various XML parsers. Therefore Stargate must base 64 encode the row key, column, qualifier, and data to be XML safe.
You can also ask for protobufs (application/x-protobuf) or binary (application/octet-stream) representations, which will not apply base 64 encoding. Protobufs is the best option. Binary has some limitations. See https://issues.apache.org/jira/browse/HBASE-1788 and https://issues.apache.org/jira/browse/HBASE-2390 for discussion of the limitations of the binary representation semantics and proposed fixes. - Andy > From: yuliya Feldman > Subject: Re: strange stargate problem > To: user@hbase.apache.org > Date: Tuesday, June 29, 2010, 10:59 PM > It looks like Base64 encoded > > Try: http://www.motobit.com/util/base64-decoder-encoder.asp > to decode the data > > > > ----- Original Message ---- > From: Eric Yang <eric...@gmail.com> > To: user@hbase.apache.org > Sent: Tue, June 29, 2010 10:29:17 PM > Subject: strange stargate problem > > Hi all, > I am playing with Hbase 0.20.5 with Stargate.
