Re: HCatOutputFormat uses Hadoop security

[Avery Ching]

HCATALOG-10 works for me, but I have a new question.  I got the error
Exception in thread "main" org.apache.hcatalog.common.HCatException : 
2001 : Error setting output information. Cause : NoSuchObjectException

from

    at 
org.apache.hcatalog.mapreduce.HCatOutputFormat.setOutput(HCatOutputFormat.java:184)

Seems like the table needs to be created first?

After looking at 
src/test/org/apache/hcatalog/mapreduce/HCatMapReduceTest.java, it 
appears so, but I just wanted to confirm that was a good example.

Thanks,

Avery

    Hi,

    I noticed that HCatOutputFormat uses Hadoop security classes

    import org.apache.hadoop.security.UserGroupInformation;
    import org.apache.hadoop.security.token.Token;
    import org.apache.hadoop.security.token.TokenIdentifier;
    import org.apache.hadoop.security.token.TokenSelector;
    import
    
org.apache.hadoop.security.token.delegation.AbstractDelegationTokenIdentifier;

    This causes problems for non-secure versions of Hadoop.

    Exception in thread "main" java.lang.NoClassDefFoundError:
    org/apache/hadoop/security/token/TokenSelector

    Are there any plans to support non-secure versions of Hadoop?
