Utilities.copyTablePropertiesToConf介绍

[英]Copies the storage handler proeprites configured for a table descriptor to a runtime job configuration. This differs from #copyTablePropertiesToConf(org.apache.hadoop.hive.ql.plan.TableDesc,org.apache.hadoop.mapred.JobConf)in that it does not allow parameters already set in the job to override the values from the table. This is important for setting the config up for reading, as the job may already have values in it from another table.
[中]将为表描述符配置的存储处理程序proeprites复制到运行时作业配置。这与#copyTablePropertiesToConf（org.apache.hadoop.hive.ql.plan.TableDesc，org.apache.hadoop.mapred.JobConf）不同，因为它不允许作业中已设置的参数覆盖表中的值。这对于设置要读取的配置很重要，因为作业中可能已经有来自另一个表的值。
