Hi Eugene, Glad you got it working! That probably explains it. Oracle has special handling for empty string vs null, and it probably did something weird in your migration scripts. Thanks, Darren

Hi, CDH5 includes sentry, so you should not have Sentry installed separately. You are probably getting problems because you are using CDH 4 sentry binaries with CDH5 configuration and code. Deactivate Sentry and restart your cluster. Thanks, Darren

How are you installing CDH 5? Manually? Via CM wizard? Are you using packages or parcels? What repository are you using for packages / parcels? It is very strange that you have some cdh5 packages but not zookeeper or solr. You should try running Host Inspector when you think everything in CDH has been uninstalled to ensure that CM agrees it is all uninstalled.

Hi Fletcher, I'm not in QA, nor in that office, so can't offer much insight here, unfortunately. Your inteverviewers should be able to give you the best idea of how the culture is. We can discuss further on LinkedIn. Thanks, Darren

Your yum info zookeeper shows that the packages is available, not installed (that's "Available Packages" means). Was there more text from "yum info zookeeper" other than what you included here? yum can list both available and installed packages. Does /usr/lib/zookeeper exist? It should not, if zookeeper is not installed. If it exists, what does the file /usr/lib/zookeeper/cloudera/cdh_version.properties say? If these exist, but yum doesn't think zookeeper is installed, then your machine somehow got put into a bad state where files exist for packages that are not installed, and you'll need to figure out how you got into that state and how best to fix it. Or reformat the thing, if you can. Before doing anything drastic, make sure that both yum and rpm think the package isn't installed. You can learn more about these tools elsewhere (I'm not an expert here anyway). Thanks, Darren

Good luck in your interview! As for that bug, when I tried it out, then I saw that the wizard found the host, it told me it was already managed (there's a column in the results table for this), and I could not select the check box next to its name.

Hi, This is a pretty strange situation. It seems like somehow you have an empty string in the COMMANDS table, column ARGUMENTS. From what we can tell in the code, this should be totally impossible, since we always reject attempts to set this to an empty string (Null is ok). Was this table manually modified? What kind of database are you using? To fix the problem, the following should work: 1) stop CM (sudo service cloudera-scm-server stop) 2) back up your database (just in case!) 3) log in to the database (see db host / port / database name / username / password in /etc/cloudera-scm-server/db.properties) 4) Run the following query: update PROCESSES set ARGUMENTS=NULL where ARGUMENTS=''; (note that '' is two single quote characters, not a double-quote character) 5) start CM (sudo service cloudera-scm-server start) Thanks, Darren

Hi Fletcher, Glad to hear you're interested to join! The team in Nashua covers a wide variety of areas, including both front end and back end features. You can learn more by talking with HR, as I'm not totally sure of everything done in that office. Thanks, Darren

What operating system are you using? Are you installing CDH using parcels or packages? Cloudera Manager will use whatever binaries you've told it to use. It won't try to install a different CDH version if there's a network issue. If it detects that binaries are already installed, then it will assume you've correctly installed the binaries that you want and skip that step. In rhel-based systems, you can use "yum" to see what packages are installed. For example: yum search zookeeper This is basically how you install and manage any packages on the operating system, and has nothing to do with Cloudera, but just how your operating system works. That will tell you what packages have names containing "zookeeper" and some basic information about them. You can then learn more about a specific packages using the info command: yum info zookeeper From the info command, pay careful attention to whether the package is installed or not, and what version is installed. You're trying to install CDH 5, so any package that is CDH 4 is wrong. You'll probably find that every package reported by Host Inspector as CDH 4 will also be CDH 4 in your package manager (ie yum). To uninstall something, use the appropriate command, which for yum is: yum erase zookeeper Thanks, Darren

When you couldn't connect to CM server, it may have still been booting up. It sounds like your machine is extremely slow, so this could take some time. Installing all services requires a very large amount of RAM. If you don't have at least 10GB RAM (preferably more), then I recommend only the services you really want to try out. You can also just stop the services you aren't currently using. Thanks, Darren
