@GeKas,   You are correct.   Thank you for clarifying that EXTERNAL means NOT EMBEDDED. An external database server can be on the same host as Cloudera Manager.   -Ben ... View more

@colearendt,   I haven't played with the Docker release.  Why are you kiniting from the commandline with the host principal? CM/CDH don't use the host principal. Any idea how the myfile.keytab gets created?   I guess I am curious what you are trying to do and why when you get the error. ... View more

@scld,   Since you are using AES256, the most likely reason beeline cannot find any TGT is that the Unlimited JCE policy file is not installed in the JDK that beeline is using.   Also, why did you download the binaries?  beeline ships with CDH.   @srcnblgc,   Please show us the full command you are using and the output as it appears on the screen.  It is hard to tell what you are doing/seeing.   Check the HiveServer2 logs, as well, to see if there are errors or exceptions when you are having difficulty connecting. ...

@cloudtiger,   This error looks like it comes from within the server you are starting.  I would check the log of the role you are starting.  There may be more information or context in that file or the stderr.log.  Please share the entire stderr.log and also any stack traces in the role log (HiveServer2 or Hive Metastore).   Thanks!   Ben ...

@nehanirmal,   There isn't much risk here since the apache2 package isn't necessary for hadoop itself. When you upgrade packages, you may need to skip again, but other than that, as long as you don't use the Hue Load Balancer, you shouldn't notice a problem related to skipping the package.   Ben ...

@Krish216,   Activity Monitor is only useful for MapReduce1.  It is not used if you are using YARN for your jobs. So, rather than troubleshoot this, unless you are using MR1, you can safely delete the Activity Monitor instance.  It is not used for anything if you are using YARN/MR2 only.   If you are using MR1 after all, is that the complete stack or is there possible more to the logs.   Ben ...

@ludof,   The exception in the stack shows:   Caused by: java.net.SocketTimeoutException: connect timed out at java.net.PlainSocketImpl.socketConnect(Native Method) That indicates that a timeout occurred while trying to establish a connection with the server/port combination you specified.  I recommend trying to use "telnet" command to connec to the SMTP server host or port (from the Oozie host) or use tcpdump to help identify the problem.   The problem most likely lies between your Oozie host and the mail server.  Could be a firewall or some other reason the host you specified is unreachable from that location.    Here is one page that explains how to use telnet against exchnage servers to test SMTP: https://technet.microsoft.com/en-us/library/bb123686(v=exchg.160).aspx ...
