---------------------------------------------------------------
No child process exited. Either child processes could not read the
{{CQLSH_COPY_TEST_FAILURES}} environment variable, or no child process received
a sub-range of {{0 - 5000000000000000000}}, which is probably what happened.
So it looks like a test problem to me but to know for sure we need to get this
test to fail with [this
patch|https://github.com/stef1927/cassandra/tree/12024-2.1] applied, which will
print out the value of the environment variable as well as the token ranges
processed by child processes.
Feel free to take a different approach that does not depend on token ranges if
you can come up with a better idea; we basically need to select at least one
child process and tell it to exit after having processed a few token ranges.
The second part is easy, but to select a specific child process, the only
alternative I could think of is to change the parent process to pass an index
to each child process. So far we haven't gone down this route because it is a
bit invasive but if you think it is necessary and don't have any better idea,
we can alter the code to do this.
