Hi all, Lately, I have a critical problem with Kudu cluster (V1.6). For most of the queries submitted by Impala (even very simple and light one) regularly encountered with the following error. There are 120 datanode in my cluster and changed following parameters on datanodes:
unlock_experimental_flags=true rpc_service_queue_length=15000 rpc_acceptor_listen_backlog=1024 The error: > WARNINGS: Unable to advance iterator: Timed out: Scan RPC to > 172.18.77.131:7050 timed out after 0.000s (SENT): Not found: Scanner not > found Any hints and tips are appreciated. Thank you in advance. Best, Saeid
