"column": [

"index":1,

* 描述：要写入的hbase的rowkey列。index：指定该列对应reader端column的索引，从0开始，若为常量index为－1；type：指定写入数据类型，用于转换HBase byte[]；value：配置常量，常作为多个字段的拼接符。hbasewriter会将rowkeyColumn中所有列按照配置顺序进行拼接作为写入hbase的rowkey，不能全为常量。配置格式如下：
```
"rowkeyColumn": [
{
"index":0,
"type":"string"

{
"index":-1,
"type":"string",
"value":"_"
}

* 描述：指定写入hbase的时间戳。支持：当前时间、指定时间列，指定时间，三者选一。若不配置表示用当前时间。index：指定对应reader端column的索引，从0开始，需保证能转换为long,若是Date类型，会尝试用yyyy-MM-dd HH:mm:ss和yyyy-MM-dd HH:mm:ss SSS去解析；若为指定时间index为－1；value：指定时间的值,long值。配置格式如下：

"versionColumn":{
"index":1
