MapR 4.0.1 platformās, tā izmantojot nepareizi libhdfs.so bibliotēku Revolution R uzņēmuma vidē konfigurācijas dēļ.
Lai novērstu šo problēmu, apstipriniet uz klasteriem MapR 4.0.1 Revolution R 7.3 ir veikti pēc uzstādīšanas konfigurācijas šādi:
"Klienta" mezglā, izveidot vietējā sistēmā katram lietotājam koplietojamo direktoriju:
1. sudo mkdir -p /var/RevoShare/mapr
3. chmod 777 /var/RevoShare/mapr
4. pievienot. /usr/lib64/revo-7.3/Scripts/RevoHadoopEnvVars.site /home/mapr/.bash_profile
KATRA darbinieka mezglā, veikt šādas izmaiņas:
# cp scaleR-hadoop-0.1-SNAPSHOT.jar /opt/mapr/hadoop/hadoop-2.4.1/share/hadoop/common/lib/ # ln -s /opt/mapr/hadoop/hadoop-0.20.2/c++/Linux-amd64-64/lib/libhdfs.so /usr/lib64
# mv /opt/mapr/hadoop/hadoop-2.4.1/lib/native/libhdfs.so /opt/mapr/hadoop/hadoop-2.4.1/lib/native/libhdfs.so.save
Revolution R instalēšana automātiski izveido saiti uz scaleR hadoop-0.1 SNAPSHOT.jar $HADOOP_HOME/bibliotēka. Tomēr tas ir nepareizi directory (ziņots kļūdas) un fails ir saistīta vai kopēt /opt/mapr/hadoop/hadoop-2.4.1/share/hadoop/common/lib/.
Saites /opt/mapr/hadoop/hadoop-0.20.2/c++/Linux-amd64-64/lib/libhdfs.so /usr/lib64 nodrošinās, ka pareizi libhdfs.so atrodas Revolution r. Trešā darbība ir nepieciešams, lai pārvietotu problēmu libhdfs.so malā.
