---------------------------------
Parent: IMPALA-5741
Issue Type: Sub-task (was: Bug)
> 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: Sub-task
> Reporter: Wenzhe Zhou
> Priority: Major
>
> 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.
