---------------------------------------------------------

I found the resolution for this issue. We need to append a parameter in the connection string in Drill storage plugin:
jdbc:db2://server:port/db{color:red}:allowNextOnExhaustedResultSet=1;{color}

>          Issue Type: Bug
>          Components: Client - JDBC, Storage - JDBC
>    Affects Versions: 1.9.0

>            Priority: Critical
>             Fix For: 1.9.0

> We have created a storage plugin in drill for DB2 database, PFB the details:
> {
>  "type": "jdbc",
>  "driver": "com.ibm.db2.jcc.DB2Driver",
>  "url": "jdbc:db2://server:port/databasename",
>  "username": "user",
>  "password": "password",
>  "enabled": true
> }
> Version of DB2 is 10.1. We are using a type 4 JDBC driver (db2jcc4.jar).
> When we try to read the data in any of the tables, the query fails with following error from drill:
> org.apache.drill.common.exceptions.UserRemoteException: DATA_READ ERROR: Failure while attempting to read from database. sql SELECT * FROM schema.table plugin DB2_PLUGIN Fragment 0:0 [Error Id: 1404544f-bb5e-439b-b1a8-679388bb344d on server:port]
> The error logs from drill have been attached.
> One interesting observation - when we put a LIMIT clause of <=1000 to the query, the query works and returns the data. Anything more than 1000 in LIMIT clause throws back the same error as above.
