Please us the API in batch mode dont run all the jobs at one go as kudu works better in batch process</P><P>2. if possible reduce the load via increasing TS and data disk</P><P>3. Also check if any TP is running like antivirus which is not recommend and can cause a huge spike in CPU</P> Fri, 15 Nov 2024 10:20:28 GMT https://community.cloudera.com/t5/Support-Questions/CPU-usage-of-kudu-tablet-server-is-high/m-p/397554#M249899 Asfahan 2024-11-15T10:20:28Z
