Method Detail

getInputFormat

org.apache.hadoop.mapred.InputFormat<org.apache.hadoop.io.NullWritable,T> getInputFormat(org.apache.hadoop.mapred.InputFormat<?,?> sourceInputFormat,
                                                                                         Deserializer serde)

close

void close()

getMemoryInfo

String getMemoryInfo()

purge

long purge()

purge is best effort and will just release the buffers that are unlocked (refCount == 0). This is typically called when the system is idle.

initCacheOnlyInputFormat

void initCacheOnlyInputFormat(org.apache.hadoop.mapred.InputFormat<?,?> inputFormat)
