apache-drill storage plugin creation failed - oracle

Question

I was trying to create a storage plugin configuration in apache-drill ( 1.6 ) for oracle jdbc. I have already copied ojdbc7.jar within the apache-drill-1.6.0/jars/3rdparty directory.
But am getting an error
Please retry: error (unable to create/ update storage)
while trying to create the storage plugin !
Here is the storage plugin configuration:
{
"type": "jdbc",
"driver": "oracle.jdbc.OracleDriver",
"url": "jdbc:oracle:thin:username/password#xx.xx.xx.xx:1521:***",
"enabled": true
}
& here is the drill-override.conf file :
drill.exec: {
cluster-id: "drillbits1",
zk.connect: "localhost:2181",
sys.store.provider.local.path="/data/drill"
}
I have restarted drill after copying ojdbc7.jar file within the drill 3rd party directory !
I found some similar issues here in stackoverflow .. ( storage_plugin failure & drill-1.3&Oracle jdbc ) But nothing worked for me !!
Do you have any idea about this ?
[ I am using apache-drill version 1.6 in distributed mode , centOS 7 & java_version 1.8 ]

Answer 1

I solved this issue by myself. Here is the changes that I did to resolve this one :
I changed my storage plugin configuration ( according to this POST )
{
"type": "jdbc",
"driver": "oracle.jdbc.driver.OracleDriver",
"url": "jdbc:oracle:thin:#<IP>:<PORT>:<SID>",
"username": "<USERNAME>",
"password": "<PASSWORD>",
"enabled": true
}
Just changed drill-override.conf
drill.exec: {
cluster-id: "drillbits1",
zk.connect: "localhost:2181",
drill.exec.sys.store.provider.local.path="/data/drill"
}
3 . Also, I replaced ojdbc7.jar with ojdbc6.jar ( I was trying to connect oracle DB version. 11.2.0.4 -
