Subject Kudu query error
Date Thu, 17 May 2018 09:36:55 GMT
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
