I am trying to add multiple STS in my cluster. However, only the instance on same host as HiveServer2 is working, the rest are not. I suspect some problem with how I have added the multiple instances. I could not find a document for this scenario.

@Sindhu I want to compute column stats too, so I tried using NOSCAN, however, hive interprets it as syntactical error. It only works for Analyze Table. How can we compute column stats ? Thank you for your effort.

Sometimes your docker instance may not be running. To check if sandbox is running: docker ps -a If not running, then try to start sandbox with docker command docker start sandbox

To Compute column stats we can use the Analyze Table...Compute statement. However, any execution in hive will trigger a mapreduce or a tez job. Is there a way we can do the same task without invoking a MR or tez job? Update: I did not quite get why one would want to do such an execution. However, I posted this as I was asked this question in an interview recently.

hive query is running for longer time, with 2 mappers and 2 Reducers. One of the reducer is taking1000 tasks and other reducer has only 1 task. Can you explain why the tasks are not evenly split between reducers

I am trying to understand how the EXPLAIN PLAN statement generates the plan for a given query. I have checked out the code from apache/github. I am unable to find any document/link that atleast points me where do I start looking in the code or atleast what steps does the explain plan perform to arrive at the query plan. Any pointers will be helpful.

I would like to know key benefits as NiFi is something I haven't explored till now. A high level overview is also fine.
