Hive:FAILED: LockException [Error 10280]: Error communicating with the metastore

1、问题示例

使用hive直接选择查看表中数据报错，而相同语句在spark-sql却不报错。

实在无力吐槽hive了，因它受伤太多了。

（1）使用hive

hive (test)> select * from t1;
FAILED: LockException [Error 10280]: Error communicating with the metastore
hive (test)> select * from t2;
FAILED: LockException [Error 10280]: Error communicating with the metastore
hive (test)> select * from t3;
FAILED: LockException [Error 10280]: Error communicating with the metastore
hive (test)> select * from t_orcfile;
FAILED: LockException [Error 10280]: Error communicating with the metastore
hive (test)> select * from t_textfile;
FAILED: LockException [Error 10280]: Error communicating with the metastore
hive (test)> select * from t_sequencefile;
FAILED: LockException [Error 10280]: Error communicating with the metastore

（2）使用spark-sql

spark-sql> select * from t1;
1 aaa
2 bbb
Time taken: 0.234 seconds, Fetched 2 row(s)
spark-sql> select * from t2;
Time taken: 0.086 seconds
spark-sql> select * from t3;
1 aaa
Time taken: 0.135 seconds, Fetched 1 row(s)
spark-sql> select * from t_orcfile;
a1 1 b1 c1
a2 2 b2 c2
a3 3 b3 c3
a4 4 b4 c4
a5 5 b5 c5
Time taken: 0.255 seconds, Fetched 5 row(s)
spark-sql> select * from t_textfile;
a1 3 b3 c3
a4 4 b4 c4
a1 1 b1 c1
a2 2 b2 c2
Time taken: 0.211 seconds, Fetched 4 row(s)
spark-sql> select * from t_sequencefile;
a1 1 b1 c1
a2 2 b2 c2
Time taken: 1.673 seconds, Fetched 2 row(s)

2、解决方案

尚未解决，确信hive-site.xml没有问题。

3、问题剖析

尚未知晓。
