flink sql 1.10.0 对hive GenericUDF支持,之前的图片在邮件组不显示,重新编辑

hi all:
&nbsp; &nbsp; &nbsp; &nbsp; 现在在做把原来离线 hive 上的任务迁移到flink sql 1.10.0的工作,之前看文档说flink 支持hive的GenericUDF,但是我发现个别在flink中报错,请问是我哪里设置有问题么?
&nbsp; &nbsp; &nbsp; &nbsp; 比如current_timestamp()
&nbsp; &nbsp; &nbsp; &nbsp; 在hive中语句:
select from_unixtime(unix_timestamp(current_timestamp()),'yyyyMMddHHmmss');正常执行
&nbsp; &nbsp; &nbsp; 而提交flink sql 任务报错

语句都是一样的为啥就跑错了,请大家给点思路。

 Hi,

GenericUDFUnixTimeStamp 这个UDF
用上了Hive的SessionState,而我们的hive-integration中目前缺少这部分的支持。
Flink也支持这个函数,你可以考虑先用Flink的函数来支持。

我创建了相关issue,会尽量在1.10.1把它修复了。
