Hi all, after running a write intensive workload on HBase (0.98) I exhausted the HDFS space. I realized that most of the HDFS space was occupied by files in the path /apps/hbase/data/oldWALs/ Apparently either the old log files were not cleaned quickly enough or they were not cleaned at all. I'm wondering if I can safely delete those files and if I can how can I do it? Manually or is there an "hbase" command?
Also as an unrelated question, where are stored the -ROOT- and -META- information in zookeeper? Kind Regards
