OpenJDK 64-Bit Server VM warning: Using the ParNew young collector with the Serial old collector is deprecated and will likely be removed in a future release

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.

解决方法：
hive下lib中jar：/work/apache-hive-2.3.7-bin/lib
hadoop下lib中jar：/work/hadoop-2.7.7/share/hadoop/common/lib

对比hive和hadoop中guava*.jar版本是否匹配，hive中的jar按照hadoop中的jar保持版本一致。
