Today I ran into this same issue but the solutions in the post didn't resolve the problem.  I found each time you would start cloudera-scm-server (sudo systemctl start cloudera-scm-server) it would just add the entries back to the database we are instructed to delete.     The following did resolve the problem - Edit /var/lib/cloudera-scm-server/certmanager/cm_init.txt Change the following top 3 lines from true to false as follows. setsettings AGENT_TLS false setsettings WEB_TLS false setsettings NEED_AGENT_VALIDATION false   Then stop and start the cloudera-scm-server. This time you will see the entries back in the DB but they'll be set to false. On the database server you can run the following to confirm they are set to false now. select * from CONFIGS where ATTR='web_tls'; select * from CONFIGS where ATTR='agent_tls'; ... View more

Hi,   Could you please let me know how did you resolve this. I have the same issue. I have checked for jdk, but its the same in all the other servers as well.

Please follow the below steps. Options for container size control Now comes the complicated part - there are various overlapping and very poorly documented options for setting the size of Tez containers. According to some links, the following options control how Tez jobs started by Hive behave: hive.tez.container.size – value in megabytes hive.tez.java.opts ... View more

@Shashank and @shamik,   As each person's setup is typically different I was suggesting you start a new thread or conversation. In this new thread you can explain your unique situation in terms of overall system specifications (RAM, number of processors, etc.) as well as how much of those resources have been allocated to the Quickstart VM.   As @jmartin1938 has pointed out the Quickstart VM in inherently slow due to being a single node cluster. The issue can be made worse if the VM is not allcated the appropriate resources or used for large scale projects.    To start a new thread go to the appropriate board and use the "new message" button.    This will open a page for you to post the wording and title for the new thread.  ...

I've discovered by painful experience that this might be caused by having more than one oracle java installed, and even worse, any version of openjdk java. Namely, make sure you have added the ca you used for the ssl to the java keystore of the java version you are using (you can find that out in process list). Also, make sure that keytool you are using is belonging to this version of java - so it's best to have only one version installed, or (if that is unavoidable), use the full path to keytool. Hope it helps. ... View more
