问题描述

蜂巢2.3.9
Ubuntu16.04.3-64 位

我已经启动了 hadoop：

hadoop@ubuntu:~/hadoop/sbin$ ./start-all.sh
Starting namenodes on [localhost]
Starting datanodes
Starting secondary namenodes [ubuntu]
Starting resourcemanager
Starting nodemanagers

并在hdfs中创建/tmp/hive文件夹，并授予/tmp所有权限：

$ cd $HADOOP_HOME/bin
$ ./hadoop fs -mkdir -p /tmp/hive
$ ./hadoop fs -chmod -R 777 /tmp

$ /home/hadoop/hadoop/bin/hadoop fs -ls /tmp
Found 2 items
drwxrwxrwx   - hadoop supergroup          0 2021-06-29 17:58 /tmp/hadoop-yarn
drwxrwxrwx   - hadoop supergroup          0 2021-07-06 16:03 /tmp/hive

但是当我尝试启动 hive 时，它​​失败了：

hadoop@ubuntu:/home/hive/hive$ bin/hive
Exception in thread "main" java.lang.RuntimeException: Couldn't create directory /tmp/hive/7b9372f6-06d7-4c73-83ec-8c43db8e2c72_resources

有人可以帮忙吗？

解决方法

在 /etc/profile 中，应在下面添加

export CLASSPATH=$CLASSPATH:/home/hadoop/hadoop/lib/*:.
export CLASSPATH=$CLASSPATH:/home/hive/hive/lib/*:.
export CLASSPATH=$CLASSPATH:$DERBY_HOME/lib/derby.jar:$DERBY_HOME/lib/derbytools.jar
