Beeline是Hive 0.11引入的新的交互式CLI，基于SQLLine，可以作为Hive JDBC Client端访问Hive Server2，启动一个Beeline就是维护一个session。 Hive Server1中我们习惯了用Hive CLI，方式如下，
[trafodion@n12 udr]$ hive OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release 17/03/10 15:20:22 WARN mapreduce.TableMapReduceUtil: The hbase-prefix-tree module jar containing PrefixTreeCodec is not present.
