2) heartbeat_port 为该节点的心跳端口
3) 增加和删除节点为同步操作。这两种操作不考虑节点上已有的数据，节点直接从元数据中删除，请谨慎使用。
4) 节点下线操作用于安全下线节点。该操作为异步操作。如果成功，节点最终会从元数据中删除。如果失败，则不会完成下线。
5) 可以手动取消节点下线操作。详见 CANCEL ALTER SYSTEM
5) 可以手动取消节点下线操作。详见 CANCEL DECOMMISSION
6) Load error hub:
当前支持两种类型的 Hub：Mysql 和 Broker。需在 PROPERTIES 中指定 "type" = "mysql" 或 "type" = "broker"。
如果需要删除当前的 load error hub，可以将 type 设为 null。

## example

1. 将本地文件'testData'中的数据导入到数据库'testDb'中'testTbl'的表，使用Label用于去重
curl --location-trusted -u root -H "lable:123" -T testData http://host:port/api/testDb/testTbl/_stream_load
curl --location-trusted -u root -H "label:123" -T testData http://host:port/api/testDb/testTbl/_stream_load

2. 将本地文件'testData'中的数据导入到数据库'testDb'中'testTbl'的表，使用Label用于去重, 并且只导入k1等于20180601的数据
curl --location-trusted -u root -H "lable:123" -H "where: k1=20180601" -T testData http://host:port/api/testDb/testTbl/_stream_load
curl --location-trusted -u root -H "label:123" -H "where: k1=20180601" -T testData http://host:port/api/testDb/testTbl/_stream_load

3. 将本地文件'testData'中的数据导入到数据库'testDb'中'testTbl'的表, 允许20%的错误率（用户是defalut_cluster中的）
curl --location-trusted -u root -H "lable:123" -H "max_filter_ratio:0.2" -T testData http://host:port/api/testDb/testTbl/_stream_load
curl --location-trusted -u root -H "label:123" -H "max_filter_ratio:0.2" -T testData http://host:port/api/testDb/testTbl/_stream_load

4. 将本地文件'testData'中的数据导入到数据库'testDb'中'testTbl'的表, 允许20%的错误率，并且指定文件的列名（用户是defalut_cluster中的）
curl --location-trusted -u root -H "lable:123" -H "max_filter_ratio:0.2" -H "columns: k2, k1, v1" -T testData http://host:port/api/testDb/testTbl/_stream_load
curl --location-trusted -u root -H "label:123" -H "max_filter_ratio:0.2" -H "columns: k2, k1, v1" -T testData http://host:port/api/testDb/testTbl/_stream_load

5. 将本地文件'testData'中的数据导入到数据库'testDb'中'testTbl'的表中的p1, p2分区, 允许20%的错误率。
curl --location-trusted -u root -H "lable:123" -H "max_filter_ratio:0.2" -H "partitions: p1, p2" -T testData http://host:port/api/testDb/testTbl/_stream_load
curl --location-trusted -u root -H "label:123" -H "max_filter_ratio:0.2" -H "partitions: p1, p2" -T testData http://host:port/api/testDb/testTbl/_stream_load

6. 使用streaming方式导入（用户是defalut_cluster中的）
seq 1 10 | awk '{OFS="\t"}{print $1, $1 * 10}' | curl --location-trusted -u root -T - http://host:port/api/testDb/testTbl/_stream_load
