一些应该注意的点

如何在Hive中创建表
CREATE EXTERNAL TABLE IF NOT EXISTS roads (Name string, Layer string, Shape binary)
ROW FORMAT SERDE 'com.esri.hadoop.hive.serde.JsonSerde'
STORED AS INPUTFORMAT 'com.esri.json.hadoop.EnclosedJsonInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION '${env:HOME}/sampledata/roads';
