> Cassandra 2.2.7 introduces a regression over 2.2.6 breaking COPY ... TO STDOUT.
> In pylib/cqlshlib/copyutil.py, in CopyTask.__init__, self.printmsg is conditionally defined to EITHER a module level function accepting arguments (msg, eol=, encoding=), OR a lambda accepting arguments only (_, eol=).
> Consequently, when the lambda is in use (which requires COPY ... TO STDOUT without --debug), any attempt to call CopyTask.printmsg with an encoding parameter causes an exception.
> This occurs in ExportTask.run, thus rendering all COPY ... TO STDOUT without --debug broken.
> The fix is to update the lambda's arguments to include encoding, or better, replace it with a module-level function defined next to printmsg, so that people realize the two argument lists must be kept in sync.
> The regression was introduced in this commit:
> commit 5de9de1f5832f2a0e92783e2f4412874423e6e15
