Sam Tunnicliffe resolved CASSANDRA-10215.
-----------------------------------------
    Resolution: Fixed

Thanks, I've added more detail to the logged error message, rebased, squashed & 
committed to 3.0 in {{e097efc5f6f76a0da8d15b307301dffff79e4a35}}. dtest pr 
[here|https://github.com/riptano/cassandra-dtest/pull/538] 

Just as a note, the unit test failures are all timeouts and seem to have been 
caused by setting the default back to 60s 
([f961e84|https://github.com/apache/cassandra/commit/f961e84aa6fc139d7227e96b562e76ab857aaad0]).
 An almost identical set of failures was reported on cassci's most recent 
[3.0|http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_testall/113/testReport/]
 & 
[trunk|http://cassci.datastax.com/view/trunk/job/trunk_testall/409/testReport/] 
runs. The dtests are slightly harder to compare, due to a bug in the test 
framework, fixed in 
[51ef2e4|https://github.com/riptano/cassandra-dtest/commit/51ef2e4113cc71e6a526143644d89a2e4d2bebfc]
 before the latest run of my branch, but after the last 3.0/trunk runs. It 
doesn't look to me like any of the remaining dtest failures on the branch are 
related to this patch.

CI Tests:
* [3.0

> Once an index has been identified as being the one that should be used for a 
> given query, it should be included as part of the {{ReadCommand}} so that it 
> can be retrieved when needed during execution. Currently we don't do this, 
> meaning that the index selection process implemented in 
> {{SIM::getBestIndexFor}} is run multiple times on both the coordinator and 
> each replica when performing a range command.
> This is also a pre-requisite of CASSANDRA-10214
