> Get NPE when select from information_schema after updating storage plugins
> --------------------------------------------------------------------------
>
> Key: DRILL-1129
> URL: https://issues.apache.org/jira/browse/DRILL-1129
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Information Schema
> Reporter: Krystal
>
> git.commit.id.abbrev=5b57294
> After updating the Storage plugins from the UI, selecting from INFORMATION_SCHEMA gives a NPE. For example, I have the following setting in dfs schema:
> "default" : {
> "location" : "/drill/testdata/p1tests",
> "writable" : true,
> "storageformat" : null
> },
> I updated the location to "location" : "/drill/testdata",
> After this, I went to sqlline and ran the following query:
> 0: jdbc:drill:schema=dfs> SELECT * FROM INFORMATION_SCHEMA.`TABLES`;
> message: "Failure while running fragment. < NullPointerException"
> After I changed the location back to its previous value, the query runs successfully.
