Try putting the location to the directory the file is in. If there are
other files you don't want to be included make a subdir.

Query
select reflect('java.lang.Integer', 'parseInt', 'a', 16) from src limit 1;
throws java.lang.NoSuchMethodException: java.lang.Integer.parseInt(null, int)
A bug or a feature?
Thanks Nitin.
I also found this wiki. But it only documented the hive client log. What
about other log files created during a query?

Hi Chunky
This parameter will come into effect only if a query has been parsed to
multiple mapreduce jobs and some of them can be executed in parallel. ie all
the jobs generated by the query are not linearly dependent and hence needn't be
executed sequentially. In all other cases the MR jobs wi
by default hive reads the logging related configs from
hive-log4j.default in conf directory.

In that case, it looks like when you do a select * .. its just a cat operation.
whats the error you are getting when you put something in where clause?
If there is no error and you are not getting any result but you expect
a result then the data loaded into table is not in the format you
wanted.
this parameter is a query execution optimization approach.
hive.exec.parallel if set to true, hive determines that if few stages
of your mapreduce job can run independently and if yes then schedules
them accordingly.
If you set this value in hive-site.xml and wants to see its set or
not, then use
Hi ,
I have 2 questions regarding the parameter 'hive.exec.parallel' in
hive-site.xml in ~/.versions/hive-0.8.1/conf/
1. how do I verify from query log files or from any other way, that a
particular query is executing with this parameter set to true.
2. Is it advisable to set this parameter for r
