------------------------------------
Summary: Encrypt password in JDBC table properties when saving
into HMS DB
Key: IMPALA-12993
URL: https://issues.apache.org/jira/browse/IMPALA-12993
Project: IMPALA
Issue Type: Bug
Reporter: Wenzhe Zhou
The password of remote database is specified in table property 'dbcp.password'
when creating Impala external JDBC table. Currently all table properties are
saved in HMS DB as clear text. It's more secure to encrypt password in JDBC
table properties when saving the table metadata into HMS and decrypt it when
reading from HMS.
IMPALA-12928 makes the value of dbcp.password table property been masked in the
output of 'describe formatted' and 'show create table' commands. In Impala log
file, the password like other sensitive information within SQL statement text
can be redacted by setting up a regular expressions.
