I can not see the picture of 'hive query result', so not sure what is the real problem. But in section 2, a 'get' does not mean there is only one row, try using 'scan'. And have you tried to send the question to the hive community? They may know this better.
Thanks. -------------------Chinese below--------------- Hive查询结果的图看不到,所以不确定具体是啥问题。不过在2里面,用'get'并不能说明HBase表里只有行数据,得用scan。另外建议你给Hive社区也发邮件问问,他们可能更清楚具体是什么问题。另外建议还是尽量用英文提问,这个是国际社区,用中文的话有很多人看不懂。 谢谢。 Peng Luo <[email protected]> 于2020年1月15日周三 下午11:30写道: > Hi all, > > HBase里只有一行记录,查询row_key只有一行记录。 > > Hive创建外部表关联到HBase的这个表,能查询到2行一模一样的数据。 > > > > > > *1,HBase建表语句:* > > hbase(main):003:0> describe > 'test:table_name1' > > > COLUMN FAMILIES > DESCRIPTION > > > {NAME => 'cf', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'ROW', > REPLICATION_SCOPE => '0', COMPRESSION => 'NONE', VERSIONS => '1', TTL => > 'FOREVER', > > MIN_VERSIONS => '0', KEEP_DELETED_CELLS => 'FALSE', BLOCKSIZE => '65536', > IN_MEMORY => 'false', BLOCKCACHE => 'true'} > > 1 row(s) in 0.1370 seconds > > > > *2,HBase只有一条数据* > > hbase(main):002:0> get ' test:table_name1','7772809' > > COLUMN > CELL > > > cf:id timestamp=1579067194137, > value=777280 > > > > *3,Hive建表语句* > > drop table `test.hive_table_name1`; > > CREATE EXTERNAL TABLE `test.hive_table_name1`(`id` string ) > > ROW FORMAT SERDE > > 'org.apache.hadoop.hive.hbase.HBaseSerDe' > > STORED BY > > 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' > > WITH SERDEPROPERTIES ('hbase.columns.mapping'=':key') > > TBLPROPERTIES ('hbase.table.name'=' test:table_name1') > > > > *4,Hive查询结果* > > > > > > 我现在应该从哪些方面去尝试定位这个问题出在哪? > > >
