Hbase export - split the sequence files with specific size limit

Hello @arunr307 ,

What is the CDH version？Could you attach the full output of this command, from the command help menu there's no properties about split size：

# hbase org.apache.hadoop.hbase.mapreduce.Export
ERROR: Wrong number of arguments: 0
Usage: Export [-D <property=value>]* <tablename> <outputdir> [<versions> [<starttime> [<endtime>]] [^[regex pattern] or [Prefix] to filter]]

Note: -D properties will be applied to the conf used.
For example:
-D mapreduce.output.fileoutputformat.compress=true
-D mapreduce.output.fileoutputformat.compress.codec=org.apache.hadoop.io.compress.GzipCodec
-D mapreduce.output.fileoutputformat.compress.type=BLOCK
Additionally, the following SCAN properties can be specified
to control/limit what is exported..
-D hbase.mapreduce.scan.column.family=<family1>,<family2>, ...
-D hbase.mapreduce.include.deleted.rows=true
-D hbase.mapreduce.scan.row.start=<ROWSTART>
-D hbase.mapreduce.scan.row.stop=<ROWSTOP>
-D hbase.client.scanner.caching=100
-D hbase.export.visibility.labels=<labels>
For tables with very wide rows consider setting the batch size as below:
-D hbase.export.scanner.batch=10
-D hbase.export.scanner.caching=100
-D mapreduce.job.name=jobName - use the specified mapreduce job name for the export
For MR performance consider the following properties:
-D mapreduce.map.speculative=false
-D mapreduce.reduce.speculative=false

Thanks,

Will
