Subject Error while executing Jobs in Hive
Date Sun, 21 Sep 2014 10:06:10 GMT
Whenever I am running a hive query - select * from table. It is running
fine. But when i m trying to run a MR job for query - select count(*) from
table. It is failing with the following error -

determined at compile time: 1 In order to change the average load for a
reducer (in bytes): set hive.exec.reducers.bytes.per.reducer= In order to
limit the maximum number of reducers: set hive.exec.reducers.max= In order
to set a constant number of reducers: set mapred.reduce.tasks=
