> I can reproduce this by running a long-running query then cycling the statestore:
> {noformat}
> tarmstrong@tarmstrong-box:~/Impala/incubator-impala$ impala-shell.sh -q "select distinct * from tpch10_parquet.lineitem"
> Starting Impala Shell without Kerberos authentication
> Connected to localhost:21000
> Server version: impalad version 3.1.0-SNAPSHOT DEBUG (build c486fb9ea4330e1008fa9b7ceaa60492e43ee120)
> Query: select distinct * from tpch10_parquet.lineitem
> Query submitted at: 2018-10-04 17:06:48 (Coordinator: http://tarmstrong-box:25000)
> {noformat}
> If I kill the statestore, the query runs fine, but if I start up the statestore again, it fails.
> {noformat}
> # In one terminal, start up the statestore
> $ /home/tarmstrong/Impala/incubator-impala/be/build/latest/statestore/statestored -log_filename=statestored -log_dir=/home/tarmstrong/Impala/incubator-impala/logs/cluster -v=1 -logbufsecs=5 -max_log_files=10
> # The running query then fails
> WARNINGS: Failed due to unreachable impalad(s): tarmstrong-box:22001, tarmstrong-box:22002
> {noformat}
> Note that I've seen different subsets impalads reported as failed, e.g. "Failed due to unreachable impalad(s): tarmstrong-box:22001"
