It is a typo. 
Can you file a jira and fix it ?


Thanks,

Subject: Confusing in hive-default.xml

Hi,

Myabe it is a typo but i'm not sure.

Excerpt from hive-default.xml (trunk):
<property>
  <name>hive.input.format</name>
  <value>org.apache.hadoop.hive.ql.io.HiveInputFormat</value>
  <description>The default input format, if it is not specified, the system
assigns it. It is set to HiveInputFormat for hadoop versions 17, 18 and 19,
whereas it is set to CombinedHiveInputFormat for hadoop 20. The user can
always overwrite it - if there is a bug in CombinedHiveInputFormat, it can
always be manually set to HiveInputFormat. </description>
</property>

The 'CombinedHiveInputFormat' does not exist. It should be
'CombineHiveInputFormat' so the property's value is
'org.apache.hadoop.hive.ql.io.CombineHiveInputFormat'.

I don't know whether it's a intention or typo.

Thanks.
