[ASK] ada yang pernah konfigurasi hadoop di ubuntu? lagi ada masalah buat konfigurasi bang, awalnya di masalah user, pesan errornya gini : wx-eth0@Loco-Machinei386:~$ sudo /usr/sbin/hadoop-setup-single-node.sh Welcome to Hadoop single node setup wizard [SKIP] jawaban y semua Proceed with setup? (y/n) y chown: invalid user: `mapred:hadoop' chown: invalid user: `hdfs:hadoop' chown: invalid user: `mapred:hadoop' chown: invalid user: `hdfs:hadoop' chown: invalid user: `hdfs:hadoop' chown: invalid user: `mapred:hadoop' Configuration setup is completed. chown: invalid user: `hdfs:hadoop' dst... udah diakali dan sukses, sekarang tinggal PATH jdknya... errornya gini : Configuration setup is completed. * Formatting Apache Hadoop Name Node hadoop-namenode /usr/bin/hadoop: line 320: /usr/lib/jvm/java-6-sun/bin/java: No such file or directory /usr/bin/hadoop: line 390: /usr/lib/jvm/java-6-sun/bin/java: No such file or directory * Starting Apache Hadoop Name Node server hadoop-namenode starting namenode, logging to /var/log/hadoop/root/hadoop-root-namenode-Loco-Machinei386.out /usr/libexec/../bin/hadoop: line 320: /usr/lib/jvm/java-6-sun/bin/java: No such file or directory /usr/libexec/../bin/hadoop: line 390: /usr/lib/jvm/java-6-sun/bin/java: No such file or directory jdk saya yang terinstal : /usr/lib/jvm/java-6-openjdk-i386/ /usr/lib/jvm/java-7-openjdk-i386/ yang jadi pertanyaan, gimana cara rubah default hadoop ke openjdk? | ||

coba ganti lingkungan shell-nya, pastikan PATH untuk /bin/java itu ke openjdk. punya saya seperti ini: $ env | grep java MANPATH=/usr/local/man:/usr/man:/usr/lib/java/jre/man PATH=/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/kde4/libexec:/usr/lib/java/jre/bin:/usr/lib/qt/bin:. JAVA_HOME=/usr/lib/java | ||

kalo mau gampang, coba edit file hadoop-env.sh, edit JAVA_HOME sesuai dengan path java di komputernya, atau bisa juga tambahkan variable JAVA_HOME di bash_profile dan bashrc | ||
