Thanks for the heads up [~trichmond]!

bq. However, the version of JPAM on public repos will also cause corruption unless a single patch has been applied.
Did you mean to say "libpam4j" not JPAM in the above sentence ?

> PAM authentication is an important feature available since Hive 0.13. But Hive blog gives the following warnings:
> {quote}
> JPAM library that is used to provide the PAM authentication mode can cause HiveServer2 to go down if a user's password has expired. This happens because of segfault/core dumps from native code invoked by JPAM. Some users have also reported crashes during logins in other cases as well. Use of LDAP or KERBEROS is recommended.
> {quote}
> ​JPAM also requires user to install a native library. ​Furthermore, JPAM library seems not to have been updated since 2007.
> Other Apache projects (e.g. Ambari/Ranger/Knox) use a newer library libpam4j which doesn't require installation of native library.
