CPU usage of kudu tablet server is high

I have a total of 3 tablet servers.

Nodes with 3 tablet servers installed all have 100% CPU usage.

The cause seems to be the operation of inserting data with java's kudu api.

I'm curious as to how to fix it and what the exact cause is.

Help Me please!

Hi Team,

It does looks like too much data is writting to TS which causing it to reach 100%, did you check from TOP command how much kudu process is taking

To fix it:

1. Please us the API in batch mode dont run all the jobs at one go as kudu works better in batch process

2. if possible reduce the load via increasing TS and data disk

3. Also check if any TP is running like antivirus which is not recommend and can cause a huge spike in CPU
