30个设备，每个设备插入1万条记录，重复插入数据后，执行查询select count(*) from root align by device，报错Msg: 500: java.lang.Float cannot be cast to java.lang.Long about iotdb HOT 2 CLOSED

Thanks for your feedback.

The align by syntax will change the real series's type to the type of aggregation, i.e. the FLOAT type is transferred to Long type in this case, so while deserialize data, it will throw a such exception.

It should be fixed in the rel/0.10.

This affects 0.10.0-SNAPSHOT version and is solved in this version.
