Subject Error while reading from task log url
Date Thu, 29 Mar 2012 15:23:03 GMT
Hi
  I am able to run certain hive commands e.g. create table and select.. but
not others ..    Also my hadoop pseudo disributed cluster is working fine -
i can run the examples.

Examples of commands that fail:

insert overwrite table demographics select * from demographics_local;
Control-C  (killing a task ends up with the same error with the "Error
while reading from task log url"
