> In [this |[https://github.com/apache/nifi/commit/bbc714e73ba245de7bc32fd9958667c847101f7d] ] commit claims to add support to running multiple statements both on SelectHiveQL and PutHiveQL; instead, it adds only the support to PutHiveQL, so SelectHiveQL still lacks this important feature. @Matt Burgess, I saw that you worked on that, is there any reason for this? If not, can we support it?
