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.

Subject: Re: cmd for to know the buckets

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.

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

 show partitions xyz;      xyz(table name)

Please tell the cmd to view the buckets created....?
