Hi there
Is there any way to use arrayList of Puts in map function to insert data to
hbase ? Because,the context.write method doesn't allow to use arraylist of
puts,so in every map function I can only put one row. What can I do for
inserting some rows in each map function ?
And also how can I use autoflush & bufferclientside in Map function for
inserting data to Hbase Table ?

Give put(List<Put> puts)  a shot and see if it works for you.

Warm Regards,

You are using TableOutputFormat right? Here autoFlush is turned OFF ... You can use config param "hbase.client.write.buffer" to set the client side buffer size.

Tnx,But I don't know why when the client.buffer.size is increased, I've got
bad result,does it related to other parameters ? and I give 8 gb heap to
each regionserver.
