Is possible store BINARY data in row: string?
I have big problem:
I have row: address 36 bytes + hasz20 bytes (binary with zeros!) + 4
bytes index + 1 byte type.
I write:
304d494e454478434f494e42415345303030303030303030303030303030303030300000982051fd1e4ba744bbbe680e1fee14677ba1a3c3540bf7b1cdb606e857233e0e0000000000
and I read:
304d494e454478434f494e42415345303030303030303030303030303030303030300020203c636f310000000000000000000000000000004f494e4241534530303030303030303030
address=0MINEDxCOINBASE0000000000000000000
hash=0c0068000000000000000000000000000159a670000000000000005109227972
xio=32767, type=3
only address is correct!
address end with zero byte. Strings with zeros are not correct stored?
I store with:
auto put = std::make_unique<Put>(row);
for (int i = 0; i<qualifiers.size(); i++)
put->AddColumn(families[i], qualifiers[i], values[i]);
getTable(hTable)->Put(*std::move(put));
and read with:
return string: result->Row()

Hello Andrzej,
HBase doesn't really care what encoding you use for the key and the value.
This issue is most likely happing on the C++ client or in your application.
If you can reproduce this issue systematically with the C++ client please
feel free to open an upstream JIRA for the HBase project:
https://issues.apache.org/jira/HBASE
Thanks,
esteban.

In simple-client, we have this code:
void ValidateResult(const Result &result, const std::string &row) {
CHECK(!result.IsEmpty());
CHECK_EQ(result.Row(), row);
Are you able to reproduce what you described by modifying simple-client
(which results in assertion failure) ?
