Clock considered unsynchronized I am using below Kudu configuration and rest is default configuration. maintenance_manager_num_threads = 4 memory_limit_hard_bytes = 25 GB block_cache_capacity_mb = 4GB Also I observed , query is pointing to single tablet server instead of 3 table servers, each server has 32GB RAM. Can someone please help ASAP to solve this issue ..? thank you in advance.

Hi Rahul,

 

The error you encountered "Service unavailable: Error reading clock. Clock considered unsynchronized" means either the NTP is not installed, or if the clock is reported as unsynchronized, see NTP Clock Synchronization for trouble shooting.

Best,

Hao
