It is recommended that the RPC handler count is set to 20 * log2(Cluster Size) with an upper limit of 200. Refer more details here : https://community.hortonworks.com/articles/43839/scaling-the-hdfs-namenode-part-2.html

@Joe Walton, SmartSense Gateway does not support NTLM auth. NTLM is Microsoft proprietary. Gateway supports BASIC and DIGEST for proxy authentication. We can provide assistance if you can have one of the supported auth methods.

incompatibility of HST Server and HST Gateway versions. The upload response format sent by
Hortonworks SmartSense Datalake Upload Service is updated in 1.4.x. HST Server
expects are particular format of the response from the Upload Service. HST
Server 1.4.x required HST Gateway 1.4.x to provide the right response. Solution: Verify the installed hst version
on HST Server node and the Gateway Node. Command : hst --version If SMARTSENSE-HST rpm version on
Gateway is lower than HST Server, then it has to be upgraded. HST Gateway is
backward compatible with HST Server.

@Jorge Luis Hernandez Olmos, We have seen this happen in some versions. There are some Tez analyzers that consume a lot of resources. Do this config change to disable the analyzers that consume more resources. Disabling these does not impact your normal processing or analysis. Ambari > SmartSenseConfigs> custom activity-conf :
tez_job.activity.analyzers= com.hortonworks.smartsense.activity.job.tez.analyzer.SlowNodeAnalyzer, com.hortonworks.smartsense.activity.job.tez.analyzer.LocalityAnalyzer, com.hortonworks.smartsense.activity.job.tez.analyzer.SkewAnalyzer, com.hortonworks.smartsense.activity.job.tez.analyzer.SlowestVertexAnalyzer, com.hortonworks.smartsense.activity.job.tez.analyzer.SpillAnalyzer This disables ContainerReuseAnalyzer, SlowTaskIdentifier, CriticalPathAnalyzerandShuffleTimeAnalyzer. Pls note, by default activity analysis consumes minimum of 8 GB of heap even if above analyzers are disabled. So, it is ok to see such consumption even after disabling these tez analyzers.

@Karan Alang Please try removing /var/lib/smartsense/hst-server/updates/upload/patch first and restart hst server and agents. If you still get the same error the try the same by removing /var/lib/smartsense/hst-server/updates/upload and restart.

@Saurabh B You can have multiple Activity Analyzers. So , install and start a another Activity Analyzer on the new node. You will see Activity Analyzer in the add components in Ambari. You can stop and remove the earlier Analyzer once the new Analyzer setup is completed.

@Bruce PerezVerify whether the pid at /var/run/zeppelin/zeppelin.pid is the right one for current zeppelin process.
Maybe for some reason it might have the pid of the previous Zeppelin process.
Try to update the file with the pid that Zeppelin is currently running as and then start|stop|restart|status to verify if it works.

Affected versions: 1.2.x Symptoms: Ambari was running as root during
installation, then after configured for non-root, the issue occurs. When we create a bundle, we are
not able to encrypt it because ambari is not able to read the public key under
