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.
