編譯豬0.16上HBase的1.2.5，但HbaseStorge不從源代碼工作

Question

我編譯Apache豬0.16在HBase的1.2.5如下：

ant jar -Dhadoopversion=23 -Dhbase95.version=1.2.5 

現在我想運行豬代碼如下：

A = LOAD 'test.csv' USING PigStorage('\t') as (id:chararray,note:chararray); 

STORE A into 'hbase://test_me' using org.apache.pig.backend.hadoop.hbase.HBaseStorage('id:id note:note'); 

但是當我想上面的代碼運行，我收到此錯誤：

pig script failed to validate: java.lang.RuntimeException: could not instantiate 'org.apache.pig.backend.hadoop.hbase.HBaseStorage' with arguments '[id:id note:note]'

Answer 1

HBASE需要一個鍵列，您還沒有任何一個！在你的情況，如果ID是鍵列，那麼你應該使用下面的代碼：

A = LOAD 'test.csv' USING PigStorage('\t') as (id:chararray,note:chararray); 
B = FILTER A BY SIZE(id) > 0; 
STORE B into 'hbase://test_me' using org.apache.pig.backend.hadoop.hbase.HBaseStorage('note:note'); 

注：豬會自動拾取ID列鍵。

此外，我希望你的hbase表有家庭'note'
