问题
I'm trying to get table properties like table db, name, owner, and hdfs location out of the hive metastore using the metastore client in java. I think I can get the table databases and names okay, but I can't figure out how to grab things like owner and hdfs location. Is it possible? I've been searching the doc and internet for a couple hours now and no dice.
回答1:
Could be something like that:
org.apache.hadoop.hive.metastore.api.Table table=..........;
org.apache.hadoop.hive.metastore.api.StorageDescriptor sd=table.getSd();
String loc=sd.getLocation();
String own=sd.getOwner();

If it is a partitioned table, you can do a :
describe formatted table partition(partition_name=partition_value).
It will display the underlying hdfs path and the owner of the table.

I ran the following command on my virtualbox having Cloudera CDH 5.1.0
$ hive -e "describe extended tablename"
The output of this command provides information in addition to tablename, dbname, owner, createtime, location. You can also refer the following CWIKI link for more details
