> Trust store passwords are actually not required for read operations. They're
> only needed for writing to the trust store; in reads they serve as an
> integrity check. Normal hadoop sslclient.xml files don't require the
> truststore password, but when the KMS is used it's required.
> If I don't specify a hadoop trust store password I get:
> {noformat}
> Failed to start namenode.
> java.io.IOException: java.security.GeneralSecurityException: The property
> 'ssl.client.truststore.password' has not been set in the ssl configuration
> file.
