Issue Type: Bug

Environment: HDP 2.4.0

Reporter: young
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[]);
(1,[name#youngjin],[],[])
sha1_contents_no_result = load 'hbase://test_sha1' using
org.apache.pig.backend.hadoop.hbase.HBaseStorage('3:* i:wh* d:*', '-loadKey
true') as (row_key:chararray, unpacker:map[], stats_i:map[], forgemeta:map[]);
(1,[],[whatever#true],[])
