Description

I am running Drill on CDH4.
I have created a Hive Storage plugin as follows:

{
  "type" : "hive",
  "enabled" : true,
  "configProps" : {
    "hive.metastore.uris" : "thrift://10.10.30.156:9083",
    "fs.default.name" : "hdfs://10.10.30.156:8020/",
    "hive.metastore.sasl.enabled" : "false"
  }
}

I connect to sqlline as follows:
/opt/drill/apache-drill-1.0.0-m2-incubating-SNAPSHOT/bin/sqlline -u "jdbc:drill:schema=hive;zk=10.10.30.156:2181"

When I run a query against a hive table it errors out as follows:

0: jdbc:drill:schema=hive> select * from `student`;
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while running query.[error_id: "1a2b3324-66bf-46cd-8353-2c5a7d52c2aa"
endpoint {
  address: "perfnode156.perf.lab"
  user_port: 31010
  control_port: 31011
  data_port: 31012
}
error_type: 0
message: "Failure while setting up Foreman. < AssertionError:[ Internal error: Error while applying rule DrillPushProjIntoScan, args [rel#5:ProjectRel.NONE.ANY([]).[](child=rel#4:Subset#0.ENUMERABLE.ANY([]).[],rownum=$0,name=$1,age=$2,gpa=$3,studentnum=$4), rel#2:EnumerableTableAccessRel.ENUMERABLE.ANY([]).[](table=[hive, student])] ] < IllegalArgumentException:[ Wrong FS: hdfs://perfnode156.perf.lab:8020/user/hive/warehouse/student, expected: file:/// ]"
]
Error: exception while executing query (state=,code=0)

I have even tried setting the below property in the hive storage plugin but it still errors out:
"fs.defaultFS" : "hdfs://10.10.30.156:8020/"

The exception in the drillbit.log is

2014-07-22 23:46:16,056 [4454e978-5f18-440e-97c8-1f01cf4475cf:foreman] ERROR o.a.drill.exec.work.foreman.Foreman - Error 07265edc-756e-4aa2-9bef-a244501a072e: Failure while setting up Foreman.

In the incubator-drill/contrib/storage-hive/core/src/main/java/org/apache/drill/exec/store/hive/HiveScan.java class, the error is occurring because the FileSystem object being created in the getSplits() method is pointing to file:///
This FileSystem object is being created from a JobConf object.
The contents of the JobConf object are:
Configuration: core-default.xml, core-site.xml, mapred-default.xml, mapred-site.xml, yarn-default.xml, yarn-site.xml, hdfs-default.xml, hdfs-site.xml

The fs.default.name is set to file:/// in /opt/cloudera/parcels/CDH-4.7.0-1.cdh4.7.0.p0.40/share/doc/hadoop-2.0.0+1604/hadoop-project-dist/hadoop-common/core-default.xml.
However changing that to hdfs://10.10.30.156:8020/ doesn't make any difference.
