Environment: Hadoop 1.0.4, HBase 0.94.6.1, Hive 0.12.0
Reporter: ZhuangjieZheng
Fix For: 0.13.0
When I create an hive external table for hbase, and insert data to it in hive
shell environment. It can run successfully. but after I quit the shell and try
to reconnect it with bin/hive command. The insert data operation throws
NullPointerException..
[hadoop@dn01 hive]$ bin/hive
hive> CREATE EXTERNAL TABLE `test`(`key` string, `uid` int) STORED BY
'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES
("hbase.columns.mapping" = ":key,d:uid#b")TBLPROPERTIES("hbase.table.name" =
"test");
......
hive> insert into table test select key, uid from reg;
......successfully
hive> quit;
[hadoop@dn01 hive]$ bin/hive
hive> insert into table test select key, uid from reg;
