sqoop ORC格式数据导入报错

Error: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException): No lease on /user/hive/warehouse/erp_product.db/erp_consume_project_num_report

解决方法：

修改linux打开文件最大限制

echo "fs.file-max = 65535" >> /etc/sysctl.conf 
echo "* - nofile 65535" >> /etc/security/limits.conf
sysctl -p

ulimit -n

修改hadoop配置

vi hdfs-site.xml

<property>
  <name>dfs.datanode.max.xcievers</name>
  <value>8192</value>
</property>
