Hello,

we experienced error below from jdbc dremio during load test using jmeter-5.2

VALIDATION ERROR: Column ‘f5’ not found in any table

SQL Query select f5
startLine 1
startColumn 8
endLine 1
endColumn 9

[Error Id: 3232be85-a85d-4389-a1d8-cac1f7218b03 on localhost:31010]

(org.apache.calcite.runtime.CalciteContextException) From line 1, column 8 to line 1, column 9: Column ‘f5’ not found in any table

we didn’t find any problem using jdbc dremio on dbeaver with those query. the query is quite simple just " select f5,count(*) as total from “localhive.default”.XXX group by f5" . our dremio version is /data/apps/dremio-community-11.0.0-202011171636110752-16ab953d.

hi Bali, datatype of f5 column is string. I forgot to tell you that when i execute query "select count() from fda_orc" without group by column the query r8753870c-4f1f-449e-a6c8-eba0dde1ada9.zip (8.9 KB) un well through jdbc apache jmeter. Attached file is profile for select count()

@i9um0

Do not find an error in the profile uploaded, does table fda_orc have a column called “f5”

Can you run a “select * from localhive.“default”.fda_orc” via Dremio and send us the profile?

Also send us the output of “describe formatted default.fda_orc” from Hive or Beeline

Hi Bali,

sorry I uploaded wrong job profile, here with the correct one,
one we specified column within query it will be error, but result will be ok if we query using select * or select count(*)
