Description
Cross data source queries are throwing exception. Examples include between a file and Hive table, a hive table and HBase table, 2 files of different formats.
Here is a simple example. I will add more detailed log.
select c.c_custkey from
dfs.`/home/mapr/tpch/sf-0.1_tpc-h_DataParquet/customer.parquet` c,
dfs.`/home/mapr/sample-data/userprofilejson/user1.json` u
where c.c_custkey = u.id;
user1.json is below.
{
"id":8362,
"account":
{
"name":"Alice",
"email":"Alice@gmail.com"
},
"address":
{
"street":"123 Ballmer Av",
"zipcode":"12345",
"state":"CA"
}
}
