I just noticed that if I restart the master before starting the regionserver, I still have my rows and I have "recovered.edits" logs in the master log : 2012-02-21 10:09:55,541 INFO org.apache.hadoop.hbase.regionserver.wal.HLogSplitter: Closed path hdfs:// lxc167.nightly-dev.com:9100/hbase/.META./1028785192/recovered.edits/0000000000000029079 (wrote 4 edits in 22ms) During my previous tests, I was doing the following : - kill datanode - start datanode - start regionserver - restart master (because .META. and -ROOT- were the only regions online): i did not realize that I could loose any data doing that. Here are the master logs to both cases : http://pastebin.com/KD03P0pD : master restart before regionserver http://pastebin.com/FvYaBMdm : master restart after regionserver
