         throws IOException

Specified by:

map in interface org.apache.hadoop.mapred.Mapper<org.apache.hadoop.hbase.io.ImmutableBytesWritable,org.apache.hadoop.hbase.client.Result,org.apache.hadoop.hbase.io.ImmutableBytesWritable,org.apache.hadoop.hbase.io.ImmutableBytesWritable>

Throws:

IOException

close

public void close()
           throws IOException

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException - if an I/O error occurs

configure

public void configure(org.apache.hadoop.mapred.JobConf jobConf)

Specified by:

configure in interface org.apache.hadoop.mapred.JobConfigurable
