Sorry for the late response. After giving up for a few days, I realized my mistake was that in the .odbc.ini file where I have my Hive and Impala DSNs, Hive host was pointing to dev and Impala host to prod. Silly me. Thank you for the quick response community.

@Dominic_kim, It might be more work, but it would be better to have a cluster where trust can be established. Clients expect that the server they connected to (whether FQDN, short name, or IP) will be included in the Subject Alternative Name extension or in the CN subject. Note that recent releases of CM and CDH do support wildcard certificates so I'm not sure what the problem is in your case... we would need some more specific info. That said, you can turn off validation in some places like Hue, but it is not so easily done in others. Depends on the client. For Hue, I think you can turn off all validation by setting: [desktop] ssl_validate=False If you don't have ssl_cert_ca_verify or other configuration in other sections, then they will look to the global "desktop" section setting. Restart Hue after making the change.

Edit the file /etc/hosts. It maps the hostname to the IP address. In most cases the quickstart VM gets this right, if you experience an issue restarting usually fixes it. Regards, Jim

No, restarting Cloudera Manager server and agents to pick up the new certificates should not affect any of the Hadoop cluster services. Regards, Jim

Hello Jim, That seems to have been the problem. Although the krb5.conf files were effectively identical the two Cloudera Managers had been configured by specifying the KDC by name and by IP address. We now have BDR working between two different Cloudera Managers, but not between two clusters with the same Cloudera Manager.

Hi, The speed of the compression codec is only part of the story, you should also consider the support for the codec in different parts of the Hadoop stack. Gaining slightly faster compression at the expense of compatibility is probably not a good trade off. Snappy is supported by pretty much all of the stack for example, whereas LZ4 is not currently supported by Impala. If in doubt I would stick with Snappy since it is a reasonably fast and splittable codec. If performance is an issue you're likely to find greater benefit focusing on other parts of the stack rather than data compression. Regards, Jim
