> Project: Apache IoTDB
> Issue Type: Bug

> [UDF]output data type and the data type of putting with PointCollector are different, return 500, NPE
>
> 当UDF类，定义的输出类型与transform 中PointCollector put 的类型不一致时，会抛出空指针异常，命令行返回500
> 我记得不能报500， 所以得处理一下。
>
> reproduction:
> 1. 使用附件的java类，将52行的putFloat 修改为putInt, 编译为jar，放到$IOTDB_HOME/ext/udf/下
> 2. 命令行执行下面sql:
> {code:java}
> drop database root.**;
> drop function count_sec;
> create function count_sec as "com.timecho.udf.normal.TestSessionTimeWindowAccessStrategy";
> CREATE DATABASE root.udf;
> CREATE TIMESERIES root.udf.d1.s1 WITH DATATYPE=text, ENCODING=PLAIN;
> CREATE TIMESERIES root.udf.d1.s2 WITH DATATYPE=text, ENCODING=PLAIN;
> insert into root.udf.d1 (time, s1, s2) values (1, 'udf', 'trigger'),(2, 'some' , 'old'),(3, null, 'trigger'),(9, 'udf', 'new'),(5, 'woman', 'udf'),(12, 'trigger', null),(14, 'udf', 14),(18, 'udf', 16),(21, 'trigger', 18),(24, 'udf', 20);
> select count_sec(s1, 'max_interval'=5, 'standard'='udf') from root.udf.d1;
> {code}
> 出错信息：
> {code:java}
> IoTDB> select count_sec(s1, 'max_interval'=5, 'standard'='udf') from root.udf.d1;
> Msg: 500: [INTERNAL_SERVER_ERROR(500)] Exception occurred: "select count_sec(s1, 'max_interval'=5, 'standard'='udf') from root.udf.d1". executeStatement failed. Task was cancelled.{code}
