Hive: Can't get the md5 value

[#1]

I get the following error. Any suggestions?

Hive Version: 1.5.0

hive> select md5(name) from account limit 1;

FAILED: SemanticException [Error 10011]: Line 1:7 Invalid function 'md5'

I am not aware of Hive Version 1.5.0 (do you mean Hive View?)

Anyhow, it works on Hive 1.2.1 (as of HDP 2.5)

and on Hive 2.1 (TP in HDP 2.5)

You were right, it was Hive view version, my bad The Hive version is 1.2.1000.2.4.3.0-227 and we are still on HDP 2.4 stack. It explains why the MD5 won't work.
