Ran the mapreduce jobs with
{noformat}
hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-examples*.jar wordcount -Dmapreduce.map.output.compress.codec=org.apache.hadoop.io.compress.ZStandardCodec -Dmapreduce.map.output.compress=true -Dmapreduce.output.fileoutputformat.compress=true -Dmapreduce.output.fileoutputformat.compress.codec=org.apache.hadoop.io.compress.ZStandardCodec wcin wcout-zst
hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-examples*.jar wordcount -Dmapreduce.map.output.compress.codec=org.apache.hadoop.io.compress.ZStandardCodec wcout-zst wcout-zst2
{noformat}
* Fixed the warnings for ZStandardDecompressor.c
* Updated the Building.txt
* Used the constant IO_COMPRESSION_CODEC_ZSTD_LEVEL_DEFAULT and fixed the default compression level
* Sorted out the TODO for the compression overhead.
[~jlowe] what do you think about adding a test that would go through all the codecs and run the M/R job you used as your example with the MRMiniCluster, do you think that would be worthwhile?
