s.Shared implementation of mapreduce code over multiple table snapshots.Computes size of each region for given table and given column families.Counter enumeration to count the actual rows.Convert HBase tabular data into a format that is consumable by Map/Reduce.A base forTableInputFormat
s.Extends the baseMapper
class to add the required input key and value classes.Iterate over an HBase table data, return (ImmutableBytesWritable, Result) pairs.Iterate over an HBase table data, return (ImmutableBytesWritable, Result) pairs.Extends the basicReducer
class to add the required key and value input/output classes.TableSnapshotInputFormat allows a MapReduce job to run over a table snapshot.Implementation class for InputSplit logic common between mapred and mapreduce.Implementation class for RecordReader logic common between mapred and mapreduce.A table split corresponds to a key range (low, high) and an optional scanner.Interface to convert visibility expressions into Tags for storing along with Cells in HFiles.RecordReader
