[jira] [Updated] (HIVE-8359) Map containing null values are not
correctly written in Parquet files
[ https://issues.apache.org/jira/browse/HIVE-8359?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Frédéric TERRAZZONI updated HIVE-8359:
--------------------------------------
Description:
Tried write a map<string,string> column in a Parquet file. The table should contain :
{code}
{"key3":"val3","key4":null}
{"key3":"val3","key4":null}
{"key1":null,"key2":"val2"}
{"key3":"val3","key4":null}
{"key3":"val3","key4":null}
{code}
... and when you do a query like {code}SELECT * from mytable{code}
We can see that the table is corrupted :
{code}
{"key3":"val3"}
{"key4":"val3"}
{"key3":"val2"}
{"key4":"val3"}
{"key1":"val3"}
{code}
I've not been able to read the Parquet file in our software afterwards, and consequently I suspect it to be corrupted.
For those who are interested, I generated this Parquet table from an Avro file.
