Stefania commented on CASSANDRA-11574:
--------------------------------------
I've installed Python 2.7.6 from a tarball, by following the instructions in
the first answer of this
[link|http://askubuntu.com/questions/101591/how-do-i-install-python-2-7-2-on-ubuntu],
still no luck I'm afraid.
I'm really in the dark here, let's try replacing the problematic line with
these 2 lines, maybe we get more clues:
{code}
num_processes = ImportTask.get_num_processes(16)
copy_options['numprocesses'] = int(opts.pop('numprocesses', num_processes))
{code}
As a workaround, you can also set {{num_processes}} to a reasonable default,
{{get_num_processes()}} will return the number of cores on the machine minus 1,
capped at 16, so you could set {{num_processes = 3}} on a 4 core machine for
example.
