Hi,
I imported a table in HDFS from a SQL database using SQOOP. Null values have 
been replaced by "null" string, so a row is (for instance): rowkey, value1, 
value2, null, null

After that I imported the data from HDFS to a HBase table using first 
org.apache.hadoop.hbase.mapreduce.ImportTsv and then 
org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles.
How can I manage these "null" values so that they are not imported in the HBase 
table?
Currently they are present as "null" string.

Thanks,

Alessandra
