Hive Shell öffnet nicht, wenn ich hive-site.xml hinzufügen

Question

Ich bin neu in Hadoop Ökosystem und HDFS

Ich installierte Hive folgende this Link nur diffrence ist, dass ich Version 1.2.1 installiert haben. Jedoch, wenn ich die TAR-Datei extrahiere, kann ich die hive-site.xml Datei nirgends finden. Zu diesem Zeitpunkt, wenn ich hive im Terminal eintippe, kann ich erfolgreich die Bienenstockoberteil starten.

hduser@apache-hadoop:~$ hive 

Logging initialized using configuration in jar:file:/usr/local/hive/lib/hive-common-1.2.1.jar!/hive-log4j.properties 
hive> 

Jetzt muss ich auch eine Verbindung zu Hive von einem anderen Remote-Server herstellen. Also las ich irgendwo wird die einen Bienenstock-Datei site.xml haben müssen, wo ich die ConnectionUser finden und connection

So manuell kopiert ich die hive-default.xml.template Datei und nannte es hive-site.xml

hduser@apache-hadoop:/usr/local/hive/conf$ cp hive-default.xml.template hive-site.xml 

und dann machte ich die Änderungen Angegeben here (Gleiches Tutorial Konfigurieren von hive-site.xml Abschnitt)

Allerdings, nachdem ich die hive-site.xml-Datei hinzufügen, bekomme ich diesen Fehler, wenn ich versuche zu laufen Bienenstock.

hduser@apache-hadoop:~$ hive

prüfen mysql-connector-java-5.1.32.jar ist in Ihrem hive lib Pfad dort

oder

hinzufügen

<property> 
<name>hive.aux.jars.path</name> 
<value>PATH OF mysql-connector-java-5.1.32.jar</value> 
</property> 

in hive-site.xml
