> 1. Create a managed table :

> {code:sql}
> CREATE TABLE `test`(
> `id` string)
> PARTITIONED BY (
> `dayno` string)
> ROW FORMAT SERDE
> 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
> OUTPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
> LOCATION
> 'hdfs://test-dev-hdfs/user/hive/warehouse/test.db/test'
> TBLPROPERTIES (
> 'transient_lastDdlTime'='1564731656')
> {code}
> ------------------------------------------------
> 2. Create partition's directory and put some data in it
> ------------------------------------------------
> {code:java}
> hdfs dfs -mkdir
> hdfs://test-dev-hdfs/user/hive/warehouse/test.db/test/dayno=20190802
> hdfs dfs -put test.data
> hdfs://test-dev-hdfs/user/hive/warehouse/test.db/test/dayno=20190802
> {code}
> ------------------------------------------------
> 3. Insert overwrite partition dayno=20190802
> ------------------------------------------------
> {code:sql}
> INSERT OVERWRITE TABLE test PARTITION(dayno='20190802')
> SELECT "some value";
> {code}
> ------------------------------------------------
