【原創】大數據基礎之Drill（2）Drill1.14+Hive2.1.1運行

問題

Drill最新版本是1.14，從1.13開始Drill支持hive的版本升級到2.3.2，詳見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)

強行使用Drill1.14鏈接Hive2.1.1會因爲metastore thrift接口變化致使問題，具體體現爲 show tables是空，具體報錯以下：

編譯

因而嘗試從新編譯Drill1.14，將依賴的hive版本降到2.1.1，下載代碼

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>

修改成<hive.version>2.1.1</hive.version>

從新編譯打包後發現問題依舊，經檢查發現修改版本以後只有jars/3rdparty下的3個hive相關jar從2.3.2改成2.1.1

hive-contrib-2.1.1.jar
hive-hbase-handler-2.1.1.jar
hive-metastore-2.1.1.jar

報錯的jar是drill-hive-exec-shaded-1.14.0.jar，這個jar包中包含包含hive-exec及依賴，

        <artifactId>maven-shade-plugin</artifactId>

        <configuration>

          <artifactSet>

            <includes>

              <include>org.apache.hive:hive-exec</include>

而且沒有使用配置的hive.version

    <dependency>

      <groupId>org.apache.hive</groupId>

      <artifactId>hive-exec</artifactId>

      <scope>compile</scope>

致使打進jar包中的hive-exec是2.3.2版本的，增長hive.version配置

    <dependency>

      <groupId>org.apache.hive</groupId>

      <artifactId>hive-exec</artifactId>

      <version>${hive.version}</version>

      <scope>compile</scope>

再打包，問題消失，show tables正常；

Hadoop Location

官方文檔說明以下：

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

但配置以後依然存在問題：

1）報錯

Diagnostics: File file:/user/drill/site.tar.gz does not exist
java.io.FileNotFoundException: File file:/user/drill/site.tar.gz does not exist

須要添加link

ln -s $HADOOP_HOME/etc/hadoop/core-site.xml $DRILL_SITE/core-site.xml

2）在實際查詢時會報錯找不到hdfs_name，須要添加link

ln -s $HADOOP_HOME/etc/hadoop/hdfs-site.xml $DRILL_SITE/hdfs-site.xml
