---------------------------
Summary: Configuration of store.parquet.use_new_reader in
drill-override.conf has no effect
Key: DRILL-7175
URL: https://issues.apache.org/jira/browse/DRILL-7175
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.15.0
Reporter: benj
As related in drill user mailing list
([http://mail-archives.apache.org/mod_mbox/drill-user/201904.mbox/%[email protected]%3e])
It's possible to configure any system option of Drill (sys.option) in the
drill-override.conf.
Exemple with _drill.exec.storage.file.partition.column.label_
{code:java}
drill.exec: {
cluster-id: "drillbits-test",
...
},
drill.exec.options: {
drill.exec.storage.file.partition.column.label: "drill_dir",
...
}
{code}
But the configuration of the particular option *store.parquet.use_new_reader*
in the same way has absolutly no effect.
Have no idea if this in rapport with the "Not supported in this release"
description found for this option, but it's appears at minimal strange that
it's possible to configure it with ALTER SESSION/SYSTEM and not in
drill-override.conf
As an additional point, I had a little trouble finding that the options had to
fit into *drill.exec.options:* so I propose to add in
drill-override-example.conf a sample of configuration of any option to avoid
this trouble.
Even with keeping the mention found in drill-module.conf if necessary
{code:json}
# Users are not supposed to set these options in the drill-override.conf file.
# Users should use ALTER SYSTEM and ALTER SESSION to set the options.
{code}
