how to create multi level partition in hive using sqoop

I need to create hive table having three Partitions year/month/day using Sqoop. I have checked --hive-partition-key and --hive-partition-value in sqoop. using these parameters I have created partition year like this --hive-partition-key year --hive-partition-value '2016' My question is how to pass multiple values for partition-key and partition-value to create partitions like year/month/day. 

sqoop import --connect jdbc:postgresql://localhost:7432/test_db \
  --driver org.postgresql.Driver --username pgadmin --password pgadmin@1234 \
  --table user1  \
  --fields-terminated-by '\001' \
  --lines-terminated-by '\012' \
  --hcatalog-database test \
  --hcatalog-table user1 \
  --hcatalog-partition-keys year,month,day \
  --hcatalog-partition-values '2016,08,15' \
  --verbose

we need to implement this in steps.at this Updated command: mark above you are doing two things.

creating fresh table and sqooping data ,As per my observation this will not work at a time as we have to create multilevel partitions using sqoop.

So first create just create ddl using hcatalogue to support multilevel partitioning..

step 1:

sqoop import \
--connect jdbc:oracle:thin \
--username xxxx \
--password yyyy \
--query  'select EMPNO,ENAME,MGR,HIREDATE,SAL,COMM from  t_test_emp  where  $CONDITIONS AND 1=2' \
--create-hcatalog-table \
--hcatalog-database db1 \
--hcatalog-table test_part1 \
--hcatalog-partition-keys  DEPTNO,JOB \
--hcatalog-partition-values  1,1 \
-m 1

step 2: Now insert data:

sqoop import \
--connect jdbc:oracle:thin:  \
--username xxxx  \
--password yyyy \
--table t_test_emp \
--columns EMPNO,DEPTNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM \
--hcatalog-database db1 \
--hcatalog-table test_part1 \
-m 1

and it will work..

In order to use Sqoop to import data into a multi-key partitioned Hive table, you can use the hcatalog-table feature

For instance, in your case, you could use something like this:

(...) --hcatalog-table <your_table_name> --hcatalog-partition-keys year,month,day
 --hcatalog-partition-values 2016,07,01

According to the documentation:

These two options are used to specify multiple static partition key/value pairs. In the prior releases, --hive-partition-key and --hive-partition-value options were used to specify the static partition key/value pair, but only one level of static partition keys could be provided. The options --hcatalog-partition-keys and --hcatalog-partition-values allow multiple keys and values to be provided as static partitioning keys. Multiple option values are to be separated by , (comma). For example, if the hive partition keys for the table to export/import from are defined with partition key names year, month and date and a specific partition with year=1999, month=12, day=31 is the desired partition, then the values for the two options will be as follows:

--hcatalog-partition-keys year,month,day --hcatalog-partition-values 1999,12,31
