[jira] [Created] (HUDI-314) Unable to query a multi-partitions MOR
realtime table
Wenning Ding created HUDI-314:
---------------------------------
Summary: Unable to query a multi-partitions MOR realtime table
Key: HUDI-314
URL: https://issues.apache.org/jira/browse/HUDI-314
Project: Apache Hudi (incubating)
Issue Type: Bug
Reporter: Wenning Ding
h3. Description
I created a Hudi MOR table with multiple partition keys. The partition keys are "year", "month" and "day".
While I try to query its realtime time in Hive like this:
{code:java}
SELECT * FROM hudi_multi_partitions_test_rt;
{code}
It returns:
{code:java}

h3. Investigations
For realtime table, Hudi will read partition keys from jobConf and split it with comma. Like this:
{code:java}
String partitionFields = jobConf.get(hive_metastoreConstants.META_TABLE_PARTITION_COLUMNS, ""); List<String> partitioningFields = partitionFields.length() > 0 ? Arrays.stream(partitionFields.split(",")).collect(Collectors.toList()) : new ArrayList<>();
{code}
The problem is Hudi split partitionFields with comma, but in Hive, Hive uses slash to split multiple partition keys e.g. "/year/month/day". Also I checked previous versions of Hive, they all use slash for split.
So my idea is just replace comma with slash.
