Cli returns UE on truncate when command is successful
-----------------------------------------------------
Key: CASSANDRA-3802
URL: https://issues.apache.org/jira/browse/CASSANDRA-3802
Project: Cassandra
Issue Type: Bug
Reporter: Joaquin Casares
Much like: https://issues.apache.org/jira/browse/CASSANDRA-3651
The UE is returned instead of a timeout error, but in this case, the timeout
error is returned even though the command executes successfully. Could we have
a tunable parameter to increase the timeout period?
Example stacktrace:
{noformat}
[default@cfs] truncate cleanup;
null
UnavailableException()

JNA confirmed on all machines via jinfo. Flush and snapshot confirmed to be
successful individually.
A truncate was tried again and the view from cfstats changed:

even though the UE was still thrown (as a possible TE).
After trying to truncate different cfs back-to-back, one completed successfully
and the rest all followed with successful completions.
