Re: Need some information over WAL
yes WAL is a single and common file for all regions on a region server. 
Yes to 1.
Re 2: HBase will roll over WAL files and eventually delete them when they are no longer needed.

Thanks Dhawal....

Oh... whatever i assumed with reading documents (partially).... that was
wrong...

With ur answer... i have another questions...
WAL is a single and common file for all region of a Region server.

Is this correct:
1. So all operation(including data) will go to WAL... operation by
operation....

2. Then on HDFS, HBase will have to perform delete operation on some set of
WAL files always...
