如何在HBASE中存储猪袋？

我试图做的是在

PIG

因此，我基本上做了以下工作：

//Loading some address data
CITY = LOAD '/user/root/landingzone/ADRPCDCITY.csv' using PigStorage(';')
AS (dPOST_CODE:chararray, dCITY_CODE:chararray);

//Create the BAG by grouping postal code
B = GROUP CITY by dPOST_CODE;

//Store it in HBASE
STORE B INTO 'hbase://TEST_ADDRESS_VALIDATION'
       USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
       'f1: group, f1:CITY' );

我面临的问题是，

BAG

不能被铸造到

HBASE

Map类

java.lang.ClassCastException: org.apache.pig.data.InternalCachedBag cannot be cast to                                                    java.util.Map

非常感谢你的帮助

更好 我得到了一个解决方案，我想与大家分享

CITY = LOAD '/user/root/landingzone/CITY_Test.csv' using PigStorage(';')
AS (POST_CODE:chararray, CITY_CODE:long, CITY_NAME:chararray);

A = FILTER CITY BY (POST_CODE) IS NOT NULL;

result = FOREACH A GENERATE POST_CODE, TOMAP(UPPER(CITY_NAME), CITY_CODE);

STORE result INTO 'CITY_ADDRESS_VALIDATION' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage( 'f1' );

使用TOMAP并通过hbastorage保存它，但不在那里分配映射，这样做很有效。

您能提供属于异常的堆栈跟踪吗？
