1.错误提示(没有json.jar包)

解决方法：
参考文档：https://github.com/stleary/JSON-java
下载json包： https://search.maven.org/search?q=g:org.json%20AND%20a:json&core=gav
将下载的json.tar包上传到/opt/cloudera/parcels/CDH/lib/sqoop/lib中。
2.其它CDH节点没有mysqldump命令（因为导入时加了--direct参数）
19/01/30 13:59:29 INFO mapreduce.Job: map 0% reduce 0%
19/01/30 13:59:33 INFO mapreduce.Job: Task Id : attempt_1545874390047_0006_m_000000_0, Status : FAILED

3.Sqoop缺少hive包

解决方法：
[root@jingong01 ~]# cp -a /opt/cloudera/parcels/CDH/lib/hive/lib/hive-shims* /opt/cloudera/parcels/CDH/lib/sqoop/lib/ --将hive下面的hive-shims包全部考到sqoop下面。
4.在hive中已创建表，在导入时加了创建表参数
19/01/30 14:30:20 INFO hive.HiveImport: WARN: The method class org.apache.commons.logging.impl.SLF4JLogFactory#release() was invoked.
19/01/30 14:30:20 INFO hive.HiveImport: WARN: Please see http://www.slf4j.org/codes.html#release for an explanation.

解决方法：
[hdfs@jingong01 ~]$ sqoop import --connect jdbc:mysql://172.16.8.93:3306/db_stktag --username wangying --password wangying --table t3 --target-dir /user/tong/123 --hive-import --create-hive-table --num-mappers 1 --hive-table TT3 -m 1 --split-by date --direct --去掉红色参数
5.使用sqoop抽取数据时,提示8032端口拒绝连接
19/03/19 10:22:42 INFO ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 9 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)

解决方法:
[root@node1 ~]# vim /opt/hadoop-2.8.5/etc/hadoop/yarn-site.xml
yarn.resourcemanager.address node1:8032 yarn.resourcemanager.scheduler.address node1:8030 yarn.resourcemanager.resource-tracker.address node1:8031
[root@node1 ~]#
6.使用hbase和hive时老卡在Running job不动,不向下执行
19/03/19 11:20:09 INFO mapreduce.JobSubmitter: Submitting tokens for job: job_1552965562217_0001

19/03/19 11:20:10 INFO mapreduce.Job: Running job: job_1552965562217_0001
解决方法:
[root@node1 ~]# vim /opt/hadoop-2.8.5/etc/hadoop/yarn-site.xml --限制内存,cpu的资源,并将配置文件同步到其它node,重启hadoop服务
yarn.nodemanager.resource.memory-mb 2048 yarn.nodemanager.resource.cpu-vcores 2
[root@node1 ~]#
7.将mysql数据导入到hive中报找不到hive包
19/03/19 14:34:25 INFO hive.HiveImport: Loading uploaded data into Hive
19/03/19 14:34:25 ERROR hive.HiveConfig: Could not load org.apache.hadoop.hive.conf.HiveConf. Make sure HIVE_CONF_DIR is set correctly.

解决方法:
[root@node1 ~]# vim /etc/profile --添加lib变量
export HADOOP_CLASSPATH=/opt/hive-2.3.4/lib/*
[root@node1 ~]# source /etc/profile
8.使用sqoop导入hive时提示jackson包冲突

[root@node1 ~]# cp -a /opt/hive-2.3.4/lib/jackson-* /opt/sqoop-1.4.7/lib/
9.创建表和导入数据到hive时没有使用分隔符
19/03/19 18:38:40 INFO metastore.HiveMetaStore: 0: Done cleaning up thread local RawStore
19/03/19 18:38:40 INFO HiveMetaStore.audit: ugi=root ip=unknown-ip-addr cmd=Done cleaning up thread local RawStore

at org.apache.sqoop.tool.ImportTool.importTable(ImportTool.java:537)
at org.apache.sqoop.tool.ImportTool.run(ImportTool.java:628)
解决方法:
create table t1(a int,b int) row format delimited fields terminated by '\t'; --创建表时必须加分隔符
sqoop import --connect jdbc:mysql://172.16.9.100/hive --username hive --password system --table TBL_PRIVS --target-dir /user/sqoop --direct -m 1 --fields-terminated-by '\t'
