RE: Spark-sql showing no table
Hi, I was using the show function. Now I am able to read tables through sql. As I solved this issue with three steps: 1. Copied core-site.xml,hdfs-site.xml and hive-site.xml into ZEPPELIN_HOME/conf folder. 2. Use same sqlContext object for each function 3.

Hi Vikash, if you want to render dataframe as a table with sqlContext, you will need to run z.show(tables) On Thu, Jul 14, 2016 at 1:22 PM Vikash Kumar <vikash.ku...@resilinc.com> wrote: > I am creating a sqlContext from exiting sc. > > Var tables = sqlContext.sql(“show tables”) > > > > > > *Thanks and regards,* > > *Vikash Kumar* > > > > *From:* Mohit Jaggi [mailto:mohitja...@gmail.com] > *Sent:* Wednesday, July 13, 2016 10:24 PM > *To:* users@zeppelin.apache.org > *Subject:* Re: Spark-sql showing no table > > > > make sure you use a hive context > > > > On Jul 13, 2016, at 12:42 AM, Vikash Kumar <vikash.ku...@resilinc.com> > wrote: > > > > Hi all, > > I am using spark with scala to read phoenix tables and > register as temporary table.

RE: Spark-sql showing no table
I am creating a sqlContext from exiting sc.
Var tables = sqlContext.sql("show tables")

Hi all,
I am using spark with scala to read phoenix tables and register
as temporary table. Which I am able to do.
After that when I am running query :

Its giving all possible output, but when I am running same
query with scala sqlContext ,then its not showing any table or neither giving

What should I do now because I also copied
core-site.xml,hdfs-site.xml,hbase-site.xml and hive-site.xml inot zeppelin conf
folder?
