Subject: Need some information over WAL
I have also doubt over WAL(write ahead log).
In hdfs we can write a new file or we can append to old file
I have also doubt over WAL(write ahead log).
In hdfs we can write a new file or we can append to old file.

1. WAL only logs operations not its data... just like disk journaling(ext4)
2. In case of Region Server failure... WAL replay will depends on Client to
get each operation'
