踩

error org.apache.hadoop.hive.ql.driver - failed: command has been interrupte

一、背景

在启动了hdfs和yarn和hbase和zookeeper的情况下，启动hive。启动失败，出现错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hive/ql/CommandNeedRetryException
   at java.lang.Class.forName0(Native Method)
   at java.lang.Class.forName(Class.java:348)
   at org.apache.hadoop.util.RunJar.run(RunJar.java:227)
   at org.apache.hadoop.util.RunJar.main(RunJar.java:148)
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hive.ql.CommandNeedRetryException

发现是hadoop-env.sh中的【HADOOP_CLASSPATH】的问题，进入【/opt/module/hadoop-2.8.4/etc/hadoop/】，我的hadoop-env.sh的【HADOOP_CLASSPATH】是：

export HADOOP_CLASSPATH=/opt/module/hbase-1.3.1/lib/*

二、解决

根据上面的文章，要将其改为

export HADOOP_CLASSPATH=.:$CLASSPATH:$HADOOP_CLASSPATH:$HADOOP_HOME/bin

不过我的原来的还有用，所以最终改为了：

export HADOOP_CLASSPATH=.:$CLASSPATH:$HADOOP_CLASSPATH:$HADOOP_HOME/bin:/opt/module/hbase-1.3.1/lib/*

重启集群，成功
