Doug Rohrer commented on CASSANDRA-18707:
-----------------------------------------
{quote}Doug Rohrer , I noticed you were the one who tested and extended the
wait time from 60 to 70 due to a race with a hard-coded 60-second timeout in
MigrationManager MIGRATION_DELAY_IN_MS. Any reason why 140 wouldn't be a good
idea here? {quote}
I'd suggest that I should have made it a configurable value back then, and we
should probably make it configurable now. Bumping the default to 140 seems
reasonable, but I think we should make it easier for folks with their own CI
environment to potentially bump it if they need to without having to change the
code again? Thoughts on adding a new property and defaulting _that_ to 140?
I do hate to just bump the timeout without understanding why the cluster just
hung for 47 seconds, but if we've tried to reproduce it a bunch of times and
it's just not happening it seems like the only reasonable option for now. By
making it configurable, we can try locally to reproduce and diagnose the root
cause (if there is one)
