检查步骤：

1、执行命令

oozie admin -oozie http://{oozie-host}:11000/oozie -shareliblist

　　查看oozie是否正常返回以下列表：

hive
distcp
mapreduce-streaming
spark
oozie
hcatalog
hive2
sqoop
pig

2、如果没有返回以下列表需进行Create the share lib

找到share相关目录进行打包压缩（命令示例：tar zcf share.tar.gz share），并执行一下命令生成hdfs相应目录及文件

./bin/oozie-setup.sh sharelib create -fs hdfs://hadoop01:8020 -locallib share.tar.gz

3、然后执行以下命令更新Update Sharelib，即可看到以上列表；

oozie admin -oozie http://{oozie-host}:11000/oozie -sharelibupdate

oozie的sharelib没有正确放到hadoop中，导致异常/user/oozie/share/lib does not exist
