I looked in a little more depth on this issue. Here are the findings: 1. When I use 1 HS2 behind the LoadBalancer, it succeeds without any error 2. When I use 2 HS2 behind the LoadBalancer, I see one error but it retries and succeeds 3. When I use 3 or more than 3 HS2 behind the LoadBalancer, it errors out. I have tried turning the sticky connections for TCP inside the LoadBalancer but to no avail. Looks like there's some sort of Kerberos handshake for which it comes back to the LoadBalancer. Here, it'll then hit another server and then fail.

I was able to resolve this issue by using HS2 on DataNodes. I don't have HMS HA but I do have multiple Hive Servers behind a load balancer. The problem arose when I moved the HS2 roles to application nodes (non-Datanodes) but when I moved them back to the DataNodes, these errors swiftly disappeared.

I am facing the same issue as well. How are you passing the JDBC URL to Oozie?

Suppose we have 8 DataNodes with 128 GB RAM each of which 64 GB is allocated to Impala and we add 8 more nodes of 256 GB and we intend to allocated 128 GB to Impala. My concern is, will the coordinator be smart enough to know the mem_limit of each node it sends fragments to? Are there any other known issues that come up with such a configuration? NOTE: Current CDH version is CDH 5.4.4 (Impala v2.2)

The asterisk (*) basically means that the NTP Daemon is in sync with the particular Remote Server (getting it's time from this server) Were you able to move past this issue? I'm facing a similar issue where the clocks randomly go out of sync on/off. I checked with my Network team for any firewall changes but there haven't been any.

You can either allocate more space to it or lower the monitoring thresholds through CM. Generally, you need 10+ GB free space for the logs. You can lower the monitoring thresholds by going to each service in the CM, and searching for "log space" in the Configuration To allocate more space, you can move the logs to another folder and create a symlink from the existing folder. This way, you don't need to change the log directory location in CM. Note that, you would need to stop each Service before moving the logs.

Through CM, Go to HBase >> Configuration and search for hbase-site. You should see a HBase Advanced Configuration Snippet (Safety Valve). Enter the xml in these depending on wherever you want (RegionServer, Master, REST etc). Through CM, all the non-defaults that you want to add to the hbase-site.xml must be done through the "Safety Valve".

Are you using Cloudera Manager? If so, these properties can be found in the "Configuration" page of the HDFS Service. Just search for these properties in the tab on the side. Let me know which folder are you looking at? The current configurations for each service are usually stored in /var/run/cloudera-scm-agent/process/XYZ-NameOfTheService. But, it can be only changed through the CM UI.

I'm running CDH5.4.3 using CM in my cluster. I have never used Search and I wanted to set it up using the latest SOLR package that includes Search. However, my parcels directory is pointing to an older version of SOLR. See this image here. In the parcels (using remote parcel repo), I'm pointing at http://archive.cloudera.com/search/parcels/latest/ . When going to this link, it doesn't seem to have the latest SOLR package for CDH5. I couldn't find the CDH5 related parcel for solr anywhere in archive.cloudera.
