Hive Web Service
Hi Bejoy,
I can access the databases list and the tables via browse Scheme of HWI.
and can see the Field Schema of the tables.
but when I go to List Sessions ---> Yogesh (Session I created) ---> write HQL ( say Describe tables; ) in Query box, set the ---> Result File /dev/null.
And then I submit the query then it shows message "Changes accepted"
If I click on View File of result file it open new page of /dev/null with blank text box ( no records) and if I go to next Block its again still the same.
Although If I run commands over Terminal it work well.
Please suggest.
Regards
Yogesh Kumar Dhari

Hi Shaik
AFAIK, there is no command in hive to view data in a particular bucket. If you are very much interested in viewing them, then you can do it at hdfs level. Just get into the corresponding table/partition location in hdfs, if you have n buckets then there will be n files each corresponding to a bucket.

Bejoy KS

Currently, configuring bucket num per partition is not allowed.
If you want know the bucket num of table, use 'desc extended' or 'desc formatted'

Hi users,
As i would like to know the syntax or the cmd to know the buckets.
For example for partitions as we will give the below cmd to know the partitions for a table
