问题
Drill最新版本是1.14，从1.13开始Drill支持hive的版本升级到2.3.2，详见1.13的release notes
The Hive client for Drill is updated to version 2.3.2. With the update, Drill supports queries on transactional (ACID) and non-transactional Hive bucketed ORC tables. The updated libraries are backward compatible with earlier versions of the Hive server and metastore. (DRILL-5978)
强行使用Drill1.14连接Hive2.1.1会由于metastore thrift接口变化导致问题，具体体现为 show tables是空，具体报错如下：

编译
于是尝试重新编译Drill1.14，将依赖的hive版本降到2.1.1，下载代码
http://mirror.bit.edu.cn/apache/drill/drill-1.14.0/apache-drill-1.14.0-src.tar.gz
POM
修改pom中的hive版本
<hive.version>2.3.2</hive.version>
修改为<hive.version>2.1.1</hive.version>
重新编译打包后发现问题依旧，经检查发现修改版本之后只有jars/3rdparty下的3个hive相关jar从2.3.2改为2.1.1
hive-contrib-2.1.1.jar
hive-hbase-handler-2.1.1.jar
hive-metastore-2.1.1.jar
报错的jar是drill-hive-exec-shaded-1.14.0.jar，这个jar包中包含包含hive-exec及依赖，
<artifactId>maven-shade-plugin</artifactId>
<configuration>
<artifactSet>
<includes>
<include>org.apache.hive:hive-exec</include>
并且没有使用配置的hive.version
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-exec</artifactId>
<scope>compile</scope>
导致打进jar包中的hive-exec是2.3.2版本的，增加hive.version配置
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-exec</artifactId>
<version>${hive.version}</version>
<scope>compile</scope>
再打包，问题消失，show tables正常；
Hadoop Location
官方文档说明如下：
Apache Drill users must tell Drill-on-YARN the location of your Hadoop install. Set the HADOOP_HOME environment variable in $DRILL_SITE/drillenv.sh to point to your Hadoop installation:
export HADOOP_HOME= /path/to/hadoop-home
但配置之后依然存在问题：
1）报错
Diagnostics: File file:/user/drill/site.tar.gz does not exist
java.io.FileNotFoundException: File file:/user/drill/site.tar.gz does not exist
需要添加link
ln -s $HADOOP_HOME/etc/hadoop/core-site.xml $DRILL_SITE/core-site.xml
2）在实际查询时会报错找不到hdfs_name，需要添加link
ln -s $HADOOP_HOME/etc/hadoop/hdfs-site.xml $DRILL_SITE/hdfs-site.xml
