Cassandra COPY FROM Time and Timestamp columns - time

Question

I am trying to COPY FROM a csv file, I have both 1 Timestamp and a time column.
Trying to test with a couple of rows to begin with:
cqlsh:tests> CREATE TABLE testts (
... ID int PRIMARY KEY,
... mdate timestamp,
... ttime time);
cqlsh:tests> INSERT INTO testts (ID , mdate, ttime )
... VALUES (1, '2015-10-12', '1055') ;
cqlsh:tests> INSERT INTO testts (ID , mdate, ttime )
... VALUES (2, '2014-06-25', '920') ;
cqlsh:tests> select * from testts;
id | mdate | ttime
----+--------------------------+--------------------
1 | 2015-10-12 07:00:00+0000 | 00:00:00.000001055
2 | 2014-06-25 07:00:00+0000 | 00:00:00.000000920
(2 rows)
The above works, now I try the import file
cqlsh:tests> COPY testts ( ID,
... mdate,
... ttime)
... FROM 'c:\cassandra228\testtime.csv' WITH HEADER = FALSE AND DELIMITER = ',' AND DATETIMEFORMAT='%Y/%m/%d';
Using 3 child processes
Starting copy of tests.testts with columns [id, mdate, ttime].
Failed to import 1 rows: ParseError - Failed to parse 1130 : can't interpret '1130' as a time, given up without retries
Failed to import 1 rows: ParseError - Failed to parse 1230 : can't interpret '1230' as a time, given up without retries
Failed to import 1 rows: ParseError - Failed to parse 930 : can't interpret '930' as a time, given up without retries

Processed: 3 rows; Rate: 0 rows/s; Avg. rate: 1 rows/s
3 rows imported from 1 files in 3.269 seconds (0 skipped).
My Timestamp coulmn is formatted YYYY/MM/DD , till I gave this DATETIMEFORMAT='%Y/%m/%d' I would get error on the timestamp column but after this that error stopped.
CSV file:
3,2010/02/08,930
4,2015/05/20,1130
5,2016/08/15,1230
How do I fix this.
Thanks much

Answer 1

I have check this with same schema and data with cassandra-2.2.4's cqlsh
All the value are inserted without any Error.
But with cassandra-2.2.8's cqlsh,It's giving me the same Error as yours.
You can fix the with small change in the cqlsh code.
1 . Open the copyutil.py file. In my case it was /opt/apache-cassandra-2.2.8/pylib/cqlshlib/copyutil.py
2 . Find the method convert_time() and changed it to this
def convert_time(v, **_):
try:
return Time(int(v))
except ValueError, e:
pass
return Time(v)
