Hi,
I am able to parse the input JSON file and load it into hive. I do not see
any errors with create table, so I am assuming that. But when I try to read
the data, I get null
hive select * from jobs;
OK
null
I have validated the JSON with JSONLint and Notepad++ JSON plugin and it is
a valid
* from table is as good as hdfs -cat
are you sure there is any data in the table?

Having the a column name same as the table name, is a problem due to
which I was not able to reference jobs.values.id from jobs. Changing the
table name to jobs1 resolved the semantic error.
However, the query
as a delimited serialization of what you want to
store and that's it. That would be another way to get your scalars, arrays
and structs to work.
Don't give up yet though on the JsonSerde! :) Its probably something very
easy that we just can't see.

Your issue seems familiar. Try logging out of hive session and re-login.

Hi Praveen / All,
I also have a requirement similar to the one explained (by Praveen) below:
distinct rows on a single column with corresponding data from other columns.
Hi,
I have written a script which generates JSON files, loads it into a
dictionary, adds a few attributes and uploads the modified files to HDFS.
After the files are generated, if I perform a select * from..; on the table
which points to this location, I get null, null as the result. I also

Have you tried a re-start of the cluster. Hive is a JVM process. A hang in
the JVM may cause issues like this. I have experienced a similar issue,
however, I did not get any output at all. After typing the query and
hitting enter, the prompt never returned and neither did I see any counter
Hello,
I am using sqoop to import data from oracle into hive. Below is my SQL:
nohup sqoop import --connect jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS =
(PROTOCOL = TCP)(HOST = xxx)(PORT = )) (CONNECT_DATA = (SERVER =
DEDICATED) (SERVICE_NAME = CDWQ.tms.toyota.com) (FAILOVER_MODE=
everything in the table (not feasible in most cases)
However, I still need to know how to get the exact stack trace.

Hello Experts,
I am trying to write a UDF to parse a logline and provide the output in the
form of an array. Basically I want to be able to use LATERAL VIEW explode
subsequently to make it into columns.
This is how a typical log entry looks:

Can someone please suggest if this is doable or not? Is generic udf the
only option? How would using generic vs simple udf make any difference
since I would be returning the same object either ways.
Thank you
