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.   Sebastiano Ippolito. Skype address: "sebippo"   ... View more

    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?

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. ... View more
