[解決済み] java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient をインスタンス化できません。

2022-03-03 05:56:50

質問

Hadoop 2.7.1 と apache-hive-1.2.1 がubuntu 14.0にインストールされています。

なぜこのエラーが発生するのでしょうか？
メタストアのインストールは必要ですか？
ターミナルでhiveコマンドを打つと、内部でどのようにxmlが呼び出されるのか、そのxmlの流れはどうなっているのか？
その他に必要な設定はありますか？

ubuntu 14.0のターミナルでhiveコマンドを記述していると、以下のような例外がスローされます。

 $ hive

上記のエラーを回避するために、hive-site.xmlを.xmlで作成しました。

 <configuration>

      <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/home/local/hive-metastore-dir/warehouse</value>

      </property>

    <property>
      <name>javax.jdo.option.ConnectionURL</name>
      <value>jdbc:mysql://localhost:3306/hivedb?createDatabaseIfNotExist=true</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionDriverName</name>
      <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionUserName</name>
      <value>user</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionPassword</name>
      <value>password</value>
    </property>

    <configuration>

また、環境変数を ~/.bashrc file それでもエラーは解消されない

#HIVE home directory configuration
export HIVE_HOME=/usr/local/hive/apache-hive-1.2.1-bin
export PATH="$PATH:$HIVE_HOME/bin"

解決方法は？

以下のように修正したところ、エラーもなくHive Shellを起動できるようになりました。

1. ~/.bashrc

bashrcファイルの最後に以下の環境変数を追加してください： sudo gedit ~/.bashrc

#Java Home directory configuration
export JAVA_HOME="/usr/lib/jvm/java-9-oracle"
export PATH="$PATH:$JAVA_HOME/bin"

# Hadoop home directory configuration
export HADOOP_HOME=/usr/local/hadoop
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin

export HIVE_HOME=/usr/lib/hive
export PATH=$PATH:$HIVE_HOME/bin

2. hive-site.xml

Hiveのconfディレクトリにこのファイル（hive-site.xml）を作成し、以下の内容を追加する必要があります。

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value>
</property>


<property>
  <name>javax.jdo.option.ConnectionDriverName</name>
  <value>com.mysql.jdbc.Driver</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>root</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>root</value>
</property>

<property>
  <name>datanucleus.autoCreateSchema</name>
  <value>true</value>
</property>

<property>
  <name>datanucleus.fixedDatastore</name>
  <value>true</value>
</property>

<property>
 <name>datanucleus.autoCreateTables</name>
 <value>True</value>
 </property>

</configuration>

3. また、Hiveのlibディレクトリにjarファイル(mysql-connector-java-5.1.28.jar)を配置する必要があります。

4. Hive Shellを起動するために必要なUbuntuのインストールは以下の通りです。

マイスクランブル
Hadoop
ハイブ
ジャワ

5. 実行部分。

Hadoopの全サービスを起動する：start-all.sh
すべてのHadoopサービスが稼働しているかどうかを確認するためにjpsコマンドを入力します： jps
hive シェルに入るには hive コマンドを入力します： hive
