hive 连接一段时间后报错 Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask

应该是在连接的时候就 没有对 map  和 reduce 进行内存配置

jdbc:hive2://xxxxxxx/yyyyy?mapreduce.map.memory.mb=3809;mapreduce.map.java.opts=-Xmx3428m;mapreduce.reduce.memory.mb=2560;mapreduce.reduce.java.opts=-Xmx2304m
 

eclipse换了高版本的maven插件后报错：org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project

在给eclipse换了高版本的maven插件后，引入jar包报如下的错误： 
org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project

解决方法是：help–>install new software, 然后add，添加如下链接，

http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-mavenarchiver/0.17.2/N/LATEST/

一直下一步就可以，后面提示重启eclipse，然后重启eclipse后，右击项目，点击maven–>update project， 错误就没了

使用 sqoop 创建和 mysql 相同的表结构的时候：

sqoop create-hive-table --connect jdbc:mysql://10.136.198.112:3306/questions --username root --password root --table user --hive-table hhive

报错

解决方法，添加环境变量

往 /etc/profile 最后加入 export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/*

并且刷新 source /etc/profile

然后再次执行 sqoop 语句，执行成功，但是 hive 中并没有生成表

解决方法：讲 hive/config 下的 hive-site.xml 配置文件复制到 sqoop/config 下，再次执行，成功

hive 中的表已经生成

ERROR hive.HiveConfig: Could not load org.apache.hadoop.hive.conf.HiveConf. Make sure HIVE_CONF_D...

Sqoop 导入 mysql 表中的数据到 hive，出现如下错误： 

 解决方法：
