Hey Saurabh,

I tried this command and it still gives the same error. Actually the folder
name is supplier and supplier.tbl is the csv which resided inside it. I had
it correct in the query but in mail it is wrong. So the query that I
executed was:


create external table outside_supplier (S_SUPPKEY INT, S_NAME STRING,
S_ADDRESS STRING, S_NATIONKEY INT, S_PHONE STRING, S_ACCTBAL DOUBLE,
S_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS
TEXTFILE LOCATION 'file:///mnt/h/tpc-h-impala/data/supplier';


Thanks and Regards,
Mainak.

Hi Mainak,


Can you try using this:


 create external table outside_supplier (S_SUPPKEY INT, S_NAME STRING,
S_ADDRESS STRING, S_NATIONKEY INT, S_PHONE STRING, S_ACCTBAL DOUBLE,
S_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS
TEXTFILE LOCATION 'file:///mnt/h/tpc-h-impala/data/supplier.tbl';


I assume that "supplier.tbl" is a directory and the csv file is present in
the same.


Let me know if it worked!


Thanks,


Saurabh

      Hello,

      I have just started using Hive and I was trying to create an external
      table with the csv file placed in NFS. I tried using file:// and
      local://. Both of these attempts failed with the error:

      create external table outside_supplier (S_SUPPKEY INT, S_NAME STRING,
      S_ADDRESS STRING, S_NATIONKEY INT, S_PHONE STRING, S_ACCTBAL DOUBLE,

      STORED AS TEXTFILE LOCATION
      'local://mnt/h/tpc-h-impala/data/supplier.tbl';

      FAILED: Error in metadata: MetaException(message:Got exception:
      java.io.IOException No FileSystem for scheme: local)

      and

      create external table outside_supplier (S_SUPPKEY INT, S_NAME STRING,
      S_ADDRESS STRING, S_NATIONKEY INT, S_PHONE STRING, S_ACCTBAL DOUBLE,
      S_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|'

      FAILED: Error in metadata: MetaException
      (message:file:/h/tpc-h-impala/data/supplier.tbl is not a directory or
      unable to create one)

      Am I missing some configuration? Any help would be really
      appreciated.

      Thanks and Regards,
      Mainak.
