Review comment:
Can we do the following :
int length = in.readInt();
byte[] value = new byte[length];
in.readFully(data);
String schemaStr = new String(value, "UTF-8");
This will ensure UTF encoding/decoding

Review comment:
Instead of this, can we do :
byte[] data = schema.toString.getBytes("UTF-8");
out.writeBytes(data) to ensure we don't lost UTF encoding ?
