Hi
I recently downloaded the HDP 2.1 Sandbox. I'm trying to create a simple
java program that connects to the hive server. I'm using maven with the
following dependency:
org.apache.hive
hive-jdbc
0.13.1
Here is the java program:
public class
Fyi neglected to turn off iptables .

BTW, you can also get the Hive schema and partitions (using the code from
#1)
Table table = hiveMetastoreClient.getTable(databaseName, tableName);
List schema = hiveMetastoreClient.getSchema(databaseName,
tableName);
List partitions = table.getPartitionKeys();
The HCat and Hive APIs for the schem

I am not sure about java docs... ;-]
I have spent the last three years integrating with HCat and to make it work
had to go thru the code...
So here are some samples that can be helpful to start with. If you are
using Hive 0.12.0 I would not bother with the new APIs... I had to create
some shim cla
Version 0.12.0.
I’d like to obtain the table’s schema, scan a table partition, and use the
schema to parse the rows.
I can probably figure this out by looking at the HCatalog source. My concern
was that
the HCatalog packages in the Hive distributions are excluded in the JavaDoc,
which implies
You should be able to access this information. The exact API depends on the
version of Hive/HCat. As you know earlier HCat API is being deprecated and
will be removed in Hive 0.14.0. I can provide you with the code sample if
you tell me what you are trying to do and what version of Hive you are
usi
I’m experimenting with HCatalog, and would like to be able to access tables and
their schema
from a Java application (not Hive/Pig/MapReduce). However, the API seems to be
hidden, which
leads leads me to believe that this is not a supported use case. Is HCatalog
use limited to
one of the support
Hi,
We are trying to get the data in the form of rows not in columns ..We are
able to get partial data by implementing RecordReader. Logic we have
applied is - getting the xml with start and end tag as 'Row' as the result
we get only the second row, expected is 2 rows
Refering to below xml ,
Are you trying to capture this data in one column and use XPATH with UDF to
get the data.

Last time I looked there wasn't much info available on how to reduce the
size of the logs written here (the only suggestions being delete them after
a day).
Is there anything I can do now to reduce what's logged there in the first
place?
Cheers,
Krishna
