Data Redaction

New Contributor

Hello, my name is Thomas Wong and I am doing research on Cloudera and Big Data. One of the things I was looking at was Data Masking. I was able to find a informative Cloudera article,, on this topic, however, I ran into an issue when following the instructions. After turning on Log and Query Redaction for the whole cluster and adding the three built-in regular expressions for emails, ssn, and credit card numbers, I get an error, expected string or buffer, when typing in any query in Hive and Impala. Any help would be appreciated. I haven't been able to find any other similar posts about this issue. Thank you.
