> LOAD with HBaseStorage using a mix of pure wildcards and prefixed wildcards results in empty maps for the pure wildcarded column families.
> Here is my test scenario.
> ~~ Create test HBASE table.~~
> create 'test_sha1', '3', 'i', 'd'
> put 'test_sha1', '1', '3:name', 'youngjin'
> put 'test_sha1', '1', 'i:whatever', 'true'
> put 'test_sha1', '1', 'd:forgemeta_1_whatever', 'true'
> ---
> 1. If use pure wildcarded column families then it works.
> sha1_contents_succeed = load 'hbase://test_sha1' using org.apache.pig.backend.hadoop.hbase.HBaseStorage('3:* i:* d:*', '-loadKey true') as (row_key:chararray, unpacker:map[], stats_i:map[], forgemeta:map[]);
> dump sha1_contents_succeed;
> (1,[name#youngjin],[whatever#true],[forgemeta_1_whatever#true])
> 2. If use a mix of pure wildcards and prefixed wildcards - When the last column families has prefixed wildcards - then result but only shows a prefixed wildcards column family.
> sha1_contents_no_result = load 'hbase://test_sha1' using org.apache.pig.backend.hadoop.hbase.HBaseStorage('3:* i:* d:forgemeta_1_*', '-loadKey true') as (row_key:chararray, unpacker:map[], stats_i:map[], forgemeta:map[]);
> dump sha1_contents_no_result;
> ===> (1,[],[],[forgemeta_1_whatever#true])
> If use a mix of pure wildcards and prefixed wildcards - When use a prefixed wildcards at the first or second column families.. then result but only shows a prefixed wildcards column family.
> sha1_contents_no_result = load 'hbase://test_sha1' using org.apache.pig.backend.hadoop.hbase.HBaseStorage('3:na* i:* d:*', '-loadKey true') as (row_key:chararray, unpacker:map[], stats_i:map[], forgemeta:map[]);
