Nifi putHiveStream can not push data to hive, connect refuseed

Nifi putHiveStream can not push data to hive, connect refuseed

We trying to use nifi routing data to hive. We intalled cdh 6.2.


We configed flowed as below,


109712-all.png



the putHIveStreaming config,


109665-config.png



the hive table:

109704-hive.png



the hive server configure,

109693-hive-config.png


And get error in nifi log:
