Hello shaik,
Were you able to fetch the data earlier. I mean is it
happening for the first time or you were not able to fetch the data
even once??

if you have 2 nodes and replication factor is 1 then this is a problem,
I would like to suggest minimum replication factor as 2
this would make sure that even if 1 node is down, data is served from
replicated blocks

Hi Yogesh
No issues seen on the first look. Can you run the sqoop import with --verbose
option and post in the console dump?
Are you having multiple hive installation? If so please verify whether you are
using the same hive for both SQOOP import and then for verifying data using
hive cli.
Hi Bejoy
I have confirmed hive installation its same for both
I used command echo $HIVE_HOME on both sqoop terminal and hive terminal
both result the same Path
HADOOP/hive
I am new to Hive and sqoop, would you please give an example using -verbose
option with this command
sqoop import
Hi Yogesh
Please try out this command
sqoop import --connect
jdbc:mysql://localhost:3306/Demo --username sqoop1 --password SQOOP1
-table Dummy --hive-table dummyhive --create-hive-table --hive-import
--hive-home HADOOP/hive --verbose

Hi Yogesh
Verbose option won't create any difference in operation, but gives more logging
information on console which could be helpful to search for any hints.
So please post in your console dump/log along with the sqoop import command
with verbose enabled.
Regards
Bejoy KS
Hi Yogesh
The verbose option didn't work there as there is no DEBUG logging, can you
please add the verbose to the beginning of your sqoop command?
Lemme frame a small sqoop import sample or you, Please run this command and
post in the console log
sqoop import --verbose --connect
How can I list all the views in hive? I can't seem to figure out how to
do it with HQL.
Hi Stephen
You can see the views as well along with tables using the
Show tables;
command.

Thank you, but what I need is to list only the views, or conversely,
only the actual tables.

There may be a way to select table_name's from the metastore...if so name
your views like *_view and select for those table names.
Of course if you can query the metastore there's probably an even better
way where you don't have to name you view's anything special, and just
search for a table
I've modified hive to notify jobId for monitoring purpose. Check the issue
and vote for acceptance ^^

Hi all,
I have been interested in getting the debug information and display it
to clients.
Mark,
JDBC does not talk to hive via thrift server. I shut down the thrift
server, JDBC still works. However, you might be right in the case of
non-local connection, or as they call standalone mode.
