Timestamp inside collection does not round trip

[jhellan]

Here is a csv line that cassandra-loader is unable to parse:

554aa617-b9c3-4863-8dc2-8a2cd03b2f43,"{\"feide:[email protected]\":8/11/17 10:44 AM,\"p:2a08783f-9597-42d9-9cba-91248f1150ef\":8/3/17 8:25 AM}"

The line was produced by cassandra-unloader called like so:

cassandra-unloader -host <src ip> -f /tmp/example.csv -schema "dataporten.users(userid, userid_sec_seen)"

and we called cassandra-loader like so:

cassandra-loader -host <dst ip> -f /tmp/example.csv -schema "dataporten.users(userid, userid_sec_seen)"

We expected the second column to be loaded into the database and cqlsh to show it like this:

{'feide:[email protected]': '2017-08-11 08:44:39+0000', 'p:2a08783f-9597-42d9-9cba-91248f1150ef': '2017-08-03 06:25:35+0000'}

But cassandra-loader failed to parse the timestamps:

Trouble parsing : Unparseable date: "8/11/17 10"
java.text.ParseException: Unparseable date: "8/11/17 10"
    at java.text.DateFormat.parse(DateFormat.java:366)
    ...

This column is a collection:

`userid_sec_seen map<text,timestamp>`.

We were able to load timestamp columns, but when parsing the collection column, the loader gets confused about where the date ends. We suspect that the ':' in '10:44' gets misinterpreted. Should the unloader have escaped it?
