---------------------------------------------

             Summary: AIOOBE when doing select count(*) from on a mixed cluster.
                 Key: CASSANDRA-6707
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6707
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: old nodes: Cassandra 1.2.16 from DSE 3.2.5  (unreleased)
new node: Cassandra  2.0.5 from DSE 4.0.0 (unreleased)
            Reporter: Piotr Kołaczkowski
            Assignee: Sylvain Lebresne


After upgrading one node from 1.2 to 2.0, the following query fails with timeout:

{noformat}
Connected to test at localhost:9160.
[cqlsh 4.1.0 | Cassandra 2.0.5.1-SNAPSHOT | CQL spec 3.1.1 | Thrift protocol 19.39.0]
Use HELP for help.
cqlsh> select count(*) from cfs.sblocks;
Request did not complete within rpc_timeout.
{noformat}

Table definition:
{noformat}
cqlsh> describe columnfamily cfs.sblocks;

CREATE TABLE sblocks (
  key blob,
  column1 blob,
  value blob,
  PRIMARY KEY (key, column1)
) WITH COMPACT STORAGE AND
  bloom_filter_fp_chance=0.000068 AND
  caching='KEYS_ONLY' AND
  comment='Stores blocks of information associated with a inode' AND
  dclocal_read_repair_chance=0.000000 AND
  gc_grace_seconds=864000 AND
  index_interval=128 AND
  read_repair_chance=0.100000 AND
  replicate_on_write='true' AND
  populate_io_cache_on_flush='true' AND
  default_time_to_live=0 AND

  memtable_flush_period_in_ms=0 AND
  compaction={'class': 'com.datastax.bdp.hadoop.cfs.compaction.CFSCompactionStrategy'} AND
  compression={};
{noformat}

The 1.2 node reports the following error:
{noformat}
ERROR 08:38:02,006 Exception in thread Thread[Thread-32,5,main]
