> 复现用例：
> 测试机器：私有云32g内存，8cpu。benchmark和iotdb在同一台机器。
> iotdb-env.sh ：
> MAX_HEAP_SIZE="16G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> 数据库engine参数默认：
> # enable_seq_space_compaction=true
> # enable_unseq_space_compaction=false
> # enable_cross_space_compaction=true
> 1. benchmark产生乱序数据，配置文件见附件。
> 2.benchmark执行完成后，接着在cli执行下面的4条SQL（整个复制粘贴）
> time ./sbin/start-cli.sh -e "flush "
> time ./sbin/start-cli.sh -e "select s_0,s_1,s_2,s_3,s_4,s_5 into
> root.db.dev.s_0,root.db.dev.s_1,root.db.dev.s_2,root.db.dev.s_3,root.db.dev.s_4,root.db.dev.s_5
> from root.test.g_0.d_0; "
> time ./sbin/start-cli.sh -e "select count(*) from root.test.g_0.d_0; "
> time ./sbin/start-cli.sh -e "select count(*) from root.db.dev; "
> 其中第3条sql执行失败：
> {color:#DE350B}*time ./sbin/start-cli.sh -e "select count from
> root.test.g_0.d_0; "*{color}
> 失败：
> {color:#DE350B}*Msg: 500: [INTERNAL_SERVER_ERROR(500)] Exception occurred:
> "select count(*) from root.test.g_0.d_0". executeStatement failed.
> java.io.IOException: overlapped data should be consumed first
