---------------------------------------
Resolution: Duplicate
fixed in the patch for CASSANDRA-2069
> incorrect live endpoint checks in StorageProxy.getRangeSlice() and scan()
> -------------------------------------------------------------------------
>
> Key: CASSANDRA-2132
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2132
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.1
> Reporter: Aaron Morton
>
> If a get_range_slice() is started without any live endpoints the following appears in the logs and the request fails with an ApplicationError rather than an UnavailableError
> ERROR [pool-1-thread-61] 2011-02-04 16:11:30,725 Cassandra.java (line org.apache.cassandra.thrift.Cassandra$Processor) Internal error processing get_range_slices
> java.lang.AssertionError
> at org.apache.cassandra.service.RangeSliceResponseResolver.<init>(RangeSliceResponseResolver.java:52)
> at org.apache.cassandra.service.StorageProxy.getRangeSlice(StorageProxy.java:459)
> at org.apache.cassandra.thrift.CassandraServer.get_range_slices(CassandraServer.java:473)

> I think we need to...
> - Remove the assertion in RangeSliceResponseResolver ctor
> - call handler.assureSufficientLiveNodes() after line 733 in StorageProxy.getRangeSlice()
> Also StorageProxy.scan does a manual check of the live node count at line 1016, this means does not use the special logic for DatacenterReadCallback.assureSufficientLiveNodes()
> I've not checked this in the trunk. Will not have time to work on these during the day.
