Wenzhe Zhou commented on IMPALA-12873:
--------------------------------------
Did not find document and sample how to use password to protect jcek files.
Checked source code of Hive JDBC storage. It does not use password to protect
jcek files. It's likely we don't need to do anything.
> Support password protected keystore

> IMPALA-12380 allow user to store jdbc password in a Java keystore file on
> HDFS.
> Keystores are generally password protected and so user need a password for
> accessing keystore. (See
> https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/CredentialProviderAPI.html#Keystore_Passwords).
> From the Credential API link, if keystore has a password then it can be
> accessed if password is provided using either the environment variable
> "HADOOP_CREDSTORE_PASSWORD" or a file containing password and configured in
> core-site.xml with key
> hadoop.security.credstore.java-keystore-provider.password-file (See
> https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/ProviderUtils.java#L214)
