Philip Zeyliger updated AVRO-245:
---------------------------------
Attachment: AVRO-245.patch.txt
Attaching a new version of the patch.
The utilities have been given shorter names (see below).
The debate about how to deal with newlines actually had an elegant solution: we
simply read in JSON records, no matter how they're delimited. So "1 2 3" and
"1\n2\n3\n" would be read in the same way. Newline is still standard (and used
by the "tojson" tool), but no need to special case it. Furthermore.
parser.init() is called at every record to reset the JsonGenerator, which was
causing extra spaces to occur.
This patch also inserted a bunch of checkEof() methods in JsonParser. Ideally
those wouldn't need to be at every line, but, practically, it turns out that
parser.advance() calls back into JsonParser, which calls in.nextToken(). An
alternative is to just ignore partial records at the end of files. That has
fewer ugly lines.

Available tools:
compile Generates Java code for the given schema.
fragtojson Converts binary data to JSON.
fromjson Reads in JSON (one record per line), and writes to an avro data
file.
getschema Prints out schema of an Avro data file.
induce Use reflection to induce a schema from a class or a protocol from
an interface.
jsontofrag Converts text data to an Avro binary fragment.
tojson Dumps the contents of an Avro data file as JSON, one record per
line.
