Quanlong Huang commented on IMPALA-11260:
-----------------------------------------
FWIW, I used the following one-liner command to generate the test queries
(explain-count-all-tables.sql):
{code:bash}
for d in `bin/impala-shell.sh -B -q "show databases"`; do for t in
`bin/impala-shell.sh -B -q "show tables in $d"`; do echo "explain select
count(*) from $d.$t;"; done; done > explain-count-all-tables.sql 2>/dev/null
{code}
Then run them and skip errors:
{code:bash}
bin/impala-shell.sh -B -c -f explain-count-all-tables.sql
{code}
