---------------------------------
Summary: Unable to query Hive tables from Drill on CDH4
Key: DRILL-1172
URL: https://issues.apache.org/jira/browse/DRILL-1172
Project: Apache Drill
Issue Type: Bug
Components: Storage - Hive
Environment: CDH4, CDH5, vanilla hadoop
Reporter: Amit Katti
I am running Drill on CDH4.
I have created a Hive Storage plugin as follows:
{code}
{
"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"
}
}
{code}
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:
{code}
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: exception while executing query (state=,code=0)
{code}
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

{code}
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.
