hadoop - Hive Dynamic Partition for HDFS file -


i want create external table partition column. partition column dynamic based on application id.

for example

hdfs folder location is

/local/test/log/appid=app1 /local/test/log/appid=app2 /local/test/log/appid=app3 /local/test/log/appid=app4

inside above folders, there multiple log files in csv format.

i want create hive external table partition appid, if run below query:

select * table appid='app2';

it should return me result.

so far, have created hive table, seems not working.

here show create table details:

create external table `app_log`(   `log_time` string comment 'from deserializer',   `log_src` string comment 'from deserializer',   `log_msg` string comment 'from deserializer') partitioned (   `appid` string) row format serde   'org.apache.hadoop.hive.serde2.opencsvserde' serdeproperties (   'escapechar'='\\',   'quotechar'='\"',   'separatorchar'=',') stored inputformat   'org.apache.hadoop.mapred.textinputformat' outputformat   'org.apache.hadoop.hive.ql.io.hiveignorekeytextoutputformat' location   'hdfs://local/test/log' tblproperties (   'transient_lastddltime'='1503197360')

please in creating dynamic hive partitioning external table;

ps: don't want create table using insert query;
