Hi, on the Cloudera web page the ODBC connector 2.5.x requires only these OS based-Unix: - Red Hat Enterprise Linux 5.0/6.0; - CentOS 5.0/6.0; - SUSE Linux Enterprise Server 11. If I have SunOS 5.10, the ODBC 2.5.x connector works anyway? What is the solution for this problem? I want to make query through Ascential DataStage 7.5.3 Server (on Solaris 10 - 5.10) from Impala Server (in which I have Hive tables populated) to Oracle Database. Is it possible? Regards. Thanks.

Hi, I have a single Hadoop cluster with 1 NameNode, 1 SecondaryNameNode and 3 DataNodes. I installed Cloudera Standard and I have a strange error when I launch any type of Oozie workflow through Hue, also an empty workflow.
The error in Hue WEB UI is:
" Error submitting workflow Prova_workflow_vuoto - hue
E0902: Exception occured: [failure to login] "
instead in Oozie service log the error is:
" org.apache.oozie.service.AuthorizationException: E0902: Exception occured: [failure to login] at org.apache.oozie.service.AuthorizationService.authorizeForApp(AuthorizationService.java:401) at org.apache.oozie.servlet.BaseJobServlet.checkAuthorizationForApp(BaseJobServlet.java:191) "
and in the same file there was written:
" Caused by: org.apache.oozie.service.HadoopAccessorException: E0902: Exception occured: [failure to login] at org.apache.oozie.service.HadoopAccessorService.createFileSystem(HadoopAccessorService.java:428) at org.apache.oozie.service.AuthorizationService.authorizeForApp(AuthorizationService.java:366) ... 25 more Caused by: java.io.IOException: failure to login at org.apache.hadoop.security.UserGroupInformation.getLoginUser(UserGroupInformation.java:694) at org.apache.oozie.service.HadoopAccessorService.getUGI(HadoopAccessorService.java:268) at org.apache.oozie.service.HadoopAccessorService.createFileSystem(HadoopAccessorService.java:417) ... 26 more Caused by: javax.security.auth.login.LoginException: java.lang.NullPointerException at com.ibm.security.auth.module.LinuxLoginModule.login(LinuxLoginModule.java:165) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) "
Any suggestion?
Thanks.
Sebastiano.

Hi, I made an Oozie workflow that populates 2 hive tables. Every day a workflow inserts into Hive managed tables, one managed pure and the other managed partitioned by data. In the future these tables will become big tables. In your opinion there is a limit for this tables in terms of maximu size? What is the solution for this particular problem? Regards. Sebastiano Ippolito.

Hi, in Hue I think that there is a bug. When I try to launch Oozie workflow (any type of workflow) that points with a folder that is not associated with superuser hdfs, all of the files are moved in the trash. Any advice? Regards. Sebastiano Ippolito.

Impala ODBC client comunicate with single machine or multiple machines on 21050 port? Hi, I have this configuration of Hadoop machines with Cloudera Standard: - 1 NameNode and 1 Secondary NameNode --> IP address 1 - 1 DataNode, Impalad process --> IP address 2 - 1 Datanode, Impalad process, StateStore Impala process--> IP address 3 - 1 DataNode, Cloudera Manager, Imapalad process --> IP address 4 Impala processes are installed in the 3 machines except NameNode and Secondary NameNode Machine. If I want to connect ODBC client to Impala, I need only the 21050 port opened in one of the machine such as IP address 4 or it is necessary to comunicate from external client to all 3 datanode machines? In my configuration file which is the machine that I will write into this file for 21050 port? Thanks for your answers. Sebastiano.
