I created the hive index based on hive-0.7, the stataments are as follows:
 
create index ind_userid_txt on table users(userid)as 'org.apache.hadoop.hive.ql.index.compact.CompactIndexHandler'
WITH DEFERRED REBUILD STORED AS RCFile;
ALTER INDEX ind_userid_txt ON users REBUILD;
set hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;
insert overwrite directory "/tmp/index_result" select '_bucketname','_offset' from default__users_ind_userid_txt__
where userid=1;
set hive.exec.index_file=/tmp/index_result; 
set hive.input.format=org.apache.hadoop.hive.ql.index.io.HiveIndexInputFormat;

select * from users where userid=1; 
 
the exception as follows, pls explain why throw the following exceptions,thanks.
