integration between Hive and Hbase

问题

I'm using hive over hbase to make some BI. i have already configured hive and hbase but when i run that query "select count(*) from hbase_table_2 " on Hive

hbase_table_2 is a table in hive which refer to a table in Hbase

This exception occurred:

# of failed Map Tasks exceeded allowed limit. FailedCount: 1. LastFailedTask: task_201212171838_0009_m_000000" 

java.io.IOException: java.io.IOException: org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@7d858aa0 closed

WARN org.apache.hadoop.hive.conf.HiveConf: hive-site.xml not found on CLASSPATH

I don't know where is the problem, can any one help me?
