welp! That shows what happens when you are too "intelligent" to read through the basic stuff because you think you already know it. 😞 Thank you again @Lester Martin!! 😄 ... View more

Thanks for all the great responses here and below. Yes, indeed, the worker nodes that I have all of this running on are overloaded. Taking into account the distribution of services and the underlying box resource footprint. Thanks again!! ... View more

Hi, I have got 3 node cluster running kerberized hdp 2.6.2 with Ranger but without Ranger Storm plugin. I also see the errors when I try to run command "storm list". Storm sevice check runs fine. I get the following error when I use underprivileged user account with a valid token. Any clues most apprecieted. 2290 [main] WARN o.a.s.s.a.k.ClientCallbackHandler - Could not login: the client is being asked for a password, but the client code does not currently support obtaining a password from the user. Make sure that the client is configured to use a ticket cache (using the JAAS configuration setting 'useTicketCache=true)' and restart the client. If you still get this message after that, the TGT in the ticket cache has expired and must be manually refreshed. To do so, first determine if you are using a password or a keytab. If the former, run kinit in a Unix shell in the environment of the user who is running this client using the command 'kinit <princ>' (where <princ> is the name of the client's Kerberos principal). If the latter, do 'kinit -k -t <keytab> <princ>' (where <princ> is the name of the Kerberos principal, and <keytab> is the location of the keytab file). After manually refreshing your cache, restart this client. If you continue to see this message after manually refreshing your cache, ensure that your KDC host's clock is in sync with this host's clock. 2298 [main] ERROR o.a.s.s.a.k.KerberosSaslTransportPlugin - Server failed to login in principal:javax.security.auth.login.LoginException: No password provided javax.security.auth.login.LoginException: No password provided at com.sun.security.auth.module.Krb5LoginModule.promptForPass(Krb5LoginModule.java:919) ~[?:1.8.0_112] at com.sun.security.auth.module.Krb5LoginModule.attemptAuthentication(Krb5LoginModule.java:760) ~[?:1.8.0_112] at com.sun.security.auth.module.Krb5LoginModule.login(Krb5LoginModule.java:617) ~[?:1.8.0_112] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_112] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_112] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_112] at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_112] ...

Good write-up from @Ambud Sharma plus you can visit http://storm.apache.org/releases/1.0.2/Guaranteeing-message-processing.html for info from the source. Additionally, take a peek at the picture below I just exported from our http://hortonworks.com/training/class/hdp-developer-storm-and-trident-fundamentals/ course that might help visualize all of this information. Good luck and happy Storming! ... View more

Yes, there was some messaging early this year (that it seems the Spring folks replicated on their site) which indicated a change in the certification program, but it was determined that the planned changes were being released too fast and did not give enough time for folks already preparing for the existing certification exams to complete them. It is imaginable that the certification program will continue to evolve, but our intention is to ensure adequate time to adjust will be offered whenever any future plans are introduced. Good luck on the HDPCD exam! ... View more
