Hi all, We are running out of space in our small hadoop cluster so I was checking disk usage on HDFS and I saw that most of the space was occupied by the* /hbase/oldWALs* folder.
I have checked in the "HBase Definitive Book" and others books, web-site and I have also search my issue on google but I didn't find a proper response... So I would like to know what does this folder, what is use for and also how can I free space from this folder without breaking everything... If it's related to a specific version... our cluster is under 5.3.0-1.cdh5.3.0.p0.30 from cloudera (hbase 0.98.6). Thx for your help!
