Enhanced HBaseStorage functionality to support loading dynamically named columns by column family or by column name prefixes.
Javadoc:
/**
* A HBase implementation of LoadFunc and StoreFunc.
* <P>
* Below is an example showing how to load data from HBase:
* <pre>{@code
* raw = LOAD '
hbase://SampleTable'
* USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
* 'info:first_name info:last_name friends:* info:*', '-loadKey true -limit 5')
* AS (id:bytearray, first_name:chararray, last_name:chararray, friends_map:map[], info_map:map[]);
* }</pre>
* This example loads data redundantly from the info column family just to
* illustrate usage. Note that the row key is inserted first in the result schema.
* To load only column names that start with a given prefix, specify the column
* name with a trailing '*'. For example passing <code>friends:bob_*</code> to
* the constructor in the above example would cause only columns that start with
* <i>bob_</i> to be loaded.
* <P>
* Below is an example showing how to store data into HBase:
* <pre>{@code
* copy = STORE raw INTO '
hbase://SampleTableCopy'
* USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
* 'info:first_name info:last_name friends:* info:*')
* AS (info:first_name info:last_name buddies:* info:*);
* }</pre>
* Note that STORE will expect the first value in the tuple to be the row key.
* Scalars values need to map to an explicit column descriptor and maps need to
* map to a column family name. In the above examples, the <code>friends</code>
* column family data from <code>SampleTable</code> will be written to a
* <code>buddies</code> column family in the <code>SampleTableCopy</code> table.
