推荐答案

看起来你的 Metastore 有问题.如果您使用的是默认的 hive Metastore 嵌入式 derby.异常退出时会有锁文件.如果您删除该锁定文件，此问题将得到解决

Looks like problem with your metastore. If you are using the default hive metastore embedded derby. Lock file would be there in case of abnormal exit. if you remove that lock file this issue would be solved

rm   metastore_db/*.lck
