Dave Ariens commented on SLIDER-972:
------------------------------------
I'd encourage this project to prioritize updating the docs to clearly identify
that the AM keytab doesn't get distributed. The error messages can be less
than informative. During my deployment of running HBase on Slider they were:
{code}
java.lang.RuntimeException: Failed construction of Regionserver: class
org.apache.hadoop.hbase.regionserver.HRegionServer
Caused by: java.lang.reflect.InvocationTargetException
Caused by: java.io.IOException: Login failure for user@COMPANY from keytab
/data/1/yarn/local/usercache/user/appcache/application_1459436729804_20628/container_1459436729804_20628_01_000003/keytabs/user.keytab
Caused by: javax.security.auth.login.LoginException: Unable to obtain
password from user
{code}
...and it wasn't until I hoped on a DN and realized the keytab wasn't even
there did I proceed to further investigate and ultimately find this ticket.
> allow shipping the same keytab to components and AM

> Issue Type: Bug
> Reporter: Sergey Shelukhin
>
> Right now, AM keytab is excluded from component directories. This is not
> clearly documented, and after understanding the issue one has to copy the
> same keytab with a different name to upload it. It would be useful to be able
> to upload the same keytab for both.
