现在想实现hive的删除和修改功能，hive版本1.2。
但是配置了好久总是报错，求大神们指点。
按照网上帖子配置了hive-site.xml
<property>
<name>hive.support.concurrency</name>
<value>true</value>
</property>
<property>
<name>hive.exec.dynamic.partition.mode</name>
<value>nonstrict</value>
</property>
<property>
<name>hive.txn.manager</name>
<value>org.apache.hadoop.hive.ql.lockmgr.DbTxnManager</value>
</property>
<property>
<name>hive.compactor.initiator.on</name>
<value>true</value>
</property>
<property>
<name>hive.compactor.worker.threads</name>
<value>1</value>
</property>
也在元数据里面加入了以下表和数据
INSERT INTO NEXT_LOCK_ID VALUES(1);
INSERT INTO NEXT_COMPACTION_QUEUE_ID VALUES(1);
INSERT INTO NEXT_TXN_ID VALUES(1);
COMMIT;
参考：https://blog.csdn.net/wzy0623/article/details/51483674
现在在做查询的时候直接报错
FAILED: Error in acquiring locks: Error communicating with the metastore
后台日志报错：
