beeline报OutOfMemoryError错误

问题背景与现象

beeline客户端查询大量数据时，报OutOFMemoryError：Java heap space，具体报错信息如下：

原因分析

• 客户查询大量数据，数据量过大。
• 客户在检索数据时使用select * from table_name;，进行全表查询，表内数据过多。
• beeline默认启动内存128M，查询时返回结果集过大，导致beeline无法承载导致。

解决办法

1. 执行select count(*) from table_name;前确认需要查询的数据量大小，确认是否需要在beeline中显示如此数量级的数据。
2. 如数量在一定范围内需要显示，请调整hive客户端的jvm参数， 在hive客户端目录/Hive下的component_env中添加export HIVE_OPTS=-Xmx1024M(具体数值请根据业务调整)，并重新执行source 客户端目录/bigdata_env配置环境变量。
