FileNotFoundException

[Павел Мезенцев <pa...@mezentsev.org>]

Hello all!

I tried to create simple table in hive
> create table test (a string);

But its failed:
FAILED: Error in metadata: MetaException(message:Got exception:
java.io.FileNotFoundException File file:/user/hive/warehouse/test does not
exist.)
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.DDLTask

I set up hadoop and hive locally from couderra distribution CDH3 on Ubuntu
12.04.
And use default settings.

What I do wrong?  How can I fix it?

Thank you!
Best regards

Hi Pavel
    
The issue is some how your hive client is pointing to lfs rather than hdfs. There could be two possible reasons for this, first one amd the most likeliest one is  that your hdfs 'fs.default.name' points to file:/// instead of hdfs:// . In default the value of this property is 'file:///' you need to override this property  in core-site.xml.

Second possibility is less likely, it can happen if you have overridden the value of hive.metastore.warehouse.dir in your hive-site.xml and the value is prefixed with 'file:///'

Regards
Bejoy KS

Did you setup the /usr/hive/warehouse directory in hdfs and do a chmod g+w on it? That would be required before you run any queries.
